* Cleanup and Improve NetUtils
This class had many unused methods, inconsistent names and redundant code.
This commit cleans up code, renames a few methods and constants.
The global/account setting 'api.allowed.source.cidr.list' is set
to 0.0.0.0/0,::/0 by default preserve the current behavior and thus
allow API calls for accounts from all IPv4 and IPv6 subnets.
Users can set it to a comma-separated list of IPv4/IPv6 subnets to
restrict API calls for Admin accounts to certain parts of their network(s).
This is to improve Security. Should an attacker steal the Access/Secret key
of an account he/she still needs to be in a subnet from where accounts are
allowed to perform API calls.
This is a good security measure for APIs which are connected to the public internet.

This PR fixes the issue in which there's a leak when doing API call for listing VPC with domain account and projectId=-1.
Note for reviewers: The code formatting changed so many lines in the commit but the actual change is in line 2467-2471.
Currently the logic about volume deletion seems to be that an event
should be emitted when the volume delete is requested, not when the
deletion completes.
The VolumeStateListener specifically ignores destroy events for ROOT
volumes, assuming that the ROOT volume only gets deleted when the
instance is destroyed and the UserVmManager should take care of it.
When deleting an account, all of its resources get destroyed, but the
instance expunging circumvents the UserVmManager, and thus we miss the
VOLUME_DESTROY usage event. The account manager now attempts to
propperly destroy the vm before expunging it. This way the destroy
logic is respected, including the event emission.
Added checks to prevent netwrok update when router state is unknown or when
the new offering removes a service that is in use.
Added a new param forced to the updateNetwork API. The network will
undergo a forced update when this param is set to true.
CLOUDSTACK-8751 Clean network config like firewall rules etc, when network services are removed during network update.
This feature allows root administrators to define new roles and associate API
permissions to them.
A limited form of role-based access control for the CloudStack management server
API is provided through a properties file, commands.properties, embedded in the
WAR distribution. Therefore, customizing API permissions requires unpacking the
distribution and modifying this file consistently on all servers. The old system
also does not permit the specification of additional roles.

DB-Backed Dynamic Role Based API Access Checker for CloudStack brings following
changes, features and use-cases:
- Moves the API access definitions from commands.properties to the mgmt server DB
- Allows defining custom roles (such as a read-only ROOT admin) beyond the
current set of four (4) roles
- All roles will resolve to one of the four known roles types (Admin, Resource
Admin, Domain Admin and User) which maintains this association by requiring
all new defined roles to specify a role type.
- Allows changes to roles and API permissions per role at runtime including additions or
removal of roles and/or modifications of permissions, without the need
of restarting management server(s)
Upgrade/installation notes:
- The feature will be enabled by default for new installations, existing
deployments will continue to use the older static role based api access checker
with an option to enable this feature
- During fresh installation or upgrade, the upgrade paths will add four default
roles based on the four default role types
- For ease of migration, at the time of upgrade commands.properties will be used
to add existing set of permissions to the default roles. cloud.account
will have a new role_id column which will be populated based on default roles
as well
Dynamic-roles migration tool: scripts/util/migrate-dynamicroles.py
- Allows admins to migrate to the dynamic role based checker at a future date
- Performs a harder one-way migrate and update
- Migrates rules from existing commands.properties file into db and deprecates it
- Enables an internal hidden switch to enable dynamic role based checker feature

Quota service while allowing for scalability will make sure that the cloud is
not exploited by attacks, careless use and program errors. To address this
problem, we propose to employ a quota-enforcement service that allows resource
usage within certain bounds as defined by policies and available quotas for
various entities. Quota service extends the functionality of usage server to
provide a measurement for the resources used by the accounts and domains using a
common unit referred to as cloud currency in this document. It can be configured
to ensure that your usage won’t exceed the budget allocated to accounts/domain
in cloud currency. It will let user know how much of the cloud resources he is
using. It will help the cloud admins, if they want, to ensure that a user does
not go beyond his allocated quota. Per usage cycle if a account is found to be
exceeding its quota then it is locked. Locking an account means that it will not
be able to initiat e a new resource allocation request, whether it is more
storage or an additional ip. Needless to say quota service as well as any action
on the account is configurable.
Changes from Github code review:
- Added marvin test for quota plugin API
- removed unused commented code
- debug messages in debug enabled check
- checks for nulls, fixed access to member variables and feature
- changes based on PR comments
- unit tests for UsageTypes
- unit tests for all Cmd classes
- unit tests for all service and manager impls
- try-catch-finally or try-with-resource in dao impls for failsafe db switching
- remove dead code
- add missing quota calculation case (regression fixed)
- replace tabs with spaces in pom.xmls
- quota: though default value for quota_calculated is 0, the usage server
makes it null while entering usage entries. Flipping the condition so
as to acocunt for that.
- quotatypes: fix NPE in quota type
- quota framework test fixes
- made statement period configurable
- changed default email templates to reflect the fact that exhausted quota may not result in a locked account
- added quotaUpdateCmd that refreshes quota balances and sends alerts and statements
- report quotaSummary command returns quota balance, quota usage and state for all account
- made UI framework changes to allow for text area input in edit views
- process usage entries that have greater than 0 usage
- orocess quota entries only if tariff is non zero
- if there are credit entries but no balance entry create a dummy balance entry
- remove any credit entries that are before the last balance entry
when displaying balance statement
- on a rerun the last balance is now getting added

Added a source column to the user table.
Source now has only two values UNKNOWN,LDAP with UNKNOWN being the
default and is an enum is com.cloud.User.
When the source is UNKNOWN, the old method of authenticating against all
the available authenticators is used. If a source is available, only
that particular authenticator will be used.
added overloaded methods in AccountService to createUserAccount and
createUser with source specified.
(cherry picked from commit 5da733072e)
This limits the likeliness of timing attacks against the API.
