* Fix limitation on tag matching in 'migrateVolume' with disk offering replacement
When the feature to enable disk offering replacement during volume migration was created, we were forcing the tags of the new disk offering to exact the same as the tags of the target storage poll. However, that is not how ACS manages volumes allocation. This change modifies this validation to make it consistent with volume allocation.

* Apply Daan's suggestion regarding "doesTargetStorageSupportDiskOffering" method
* fix problem
There was a concurrency problem with the “moveNetworkAclItem” API method. If two users were changing the ACL rules order at the same time, this could lead to inconsistent actions.
To solve the problem we added a “consistency check ” parameter, which is used to hold the consistency hash. This hash is created using an MD5 hash function on a String that is created with all ACL rules UUIDs concatenated in their order, which is defined via the ‘number’ field.
We also lock the editing of the ACL while executing the upgrade. This allows us to handle race conditions nicely, and present a good feedback for the user.
Currently, users are not able to change the disk offering of VMs' root volumes. It might be interesting to allow such changes, so users would be able to move a VM initially deployed in shared storage to local storage and vice versa. It is also interesting to enable changing the quality of service offered to root disks.
We are allowing only administrators to execute the change of root volumes disk offerings during volume migration between storage. Therefore, we perform all at once, the migration of storage and the disk offering to reflect the new place.

* [CLOUDSTACK-10323] Allow changing disk offering during volume migration
This is a continuation of work developed on PR #2425 (CLOUDSTACK-10240), which provided root admins an override mechanism to move volumes between storage systems types (local/shared) even when the disk offering would not allow such operation. To complete the work, we will now provide a way for administrators to enter a new disk offering that can reflect the new placement of the volume. We will add an extra parameter to allow the root admin inform a new disk offering for the volume. Therefore, when the volume is being migrated, it will be possible to replace the disk offering to reflect the new placement of the volume.
The API method will have the following parameters:
* storageid (required)
* volumeid (required)
* livemigrate(optional)
* newdiskofferingid (optional) – this is the new parameter
The expected behavior is the following:
* If “newdiskofferingid” is not provided the current behavior is maintained. Override mechanism will also keep working as we have seen so far.
* If the “newdiskofferingid” is provided by the admin, we will execute the following checks
** new disk offering mode (local/shared) must match the target storage mode. If it does not match, an exception will be thrown and the operator will receive a message indicating the problem.
** we will check if the new disk offering tags match the target storage tags. If it does not match, an exception will be thrown and the operator will receive a message indicating the problem.
** check if the target storage has the capacity for the new volume. If it does not have enough space, then an exception is thrown and the operator will receive a message indicating the problem.
** check if the size of the volume is the same as the size of the new disk offering. If it is not the same, we will ALLOW the change of the service offering, and a warning message will be logged.
We execute the change of the Disk offering as soon as the migration of the volume finishes. Therefore, if an error happens during the migration and the volume remains in the original storage system, the disk offering will keep reflecting this situation.

I found this empty test while working on other PRs. Empty/ignored tests do not help us. I am removing it. In the future, if we manage to improve these classes, we can work on unit test cases for them.
* [CLOUDSTACK-10230] User is able to change to “Guest OS type” that has been removed
Users are able to change the OS type of VMs to “Guest OS type” that has been removed. This becomes a security issue when we try to force users to use HVM VMs (Meltdown/Spectre thing). A removed “guest os type” should not be usable by any users in the cloud.
* [CLOUDSTACK-10226] CloudStack is not importing Local storage properly
CloudStack is importing as Local storage any XenServer SR that is of type LVM or EXT. This causes a problem when one wants to use both Direct attach storage and local storage. Moreover, CloudStack was not importing all of the local storage that a host has available when local storage is enabled. It was only importing the First SR it sees.
To fix the first problem we started ignoring SRs that have the flag shared=true when discovering local storages. SRs configured to be shared are used as direct attached storage, and therefore should not be imported again as local ones.
To fix the second problem, we started loading all Local storage and importing them accordingly to ACS.
* Cleanups and formatting
* [CLOUDSTACK-10314] Add Text-Field to each ACL Rule
It is interesting to have a text field (e.g. CHAR-256) added to each ACL rule, which allows to enter a "reason" for each FW Rule created. This is valuable for customer documentation, as well as best practice for an evidence towards auditing the system
* Formatting to make check style happy and code clean ups
* [CLOUDSTACK-10240] ACS cannot migrate a volume from local to shared storage.
CloudStack is logically restricting the migration of local storages to shared storage and vice versa. This restriction is a logical one and can be removed for XenServer deployments. Therefore, we will enable migration of volumes between local-shared storages in XenServers independently of their service offering. This will work as an override mechanism to the disk offering used by volumes. If administrators want to migrate local volumes to a shared storage, they should be able to do so (the hypervisor already allows that). The same the other way around.
* Cleanups implemented while working on [CLOUDSTACK-10240]
* Fix test case test_03_migrate_options_storage_tags
The changes applied were:
- When loading hypervisors capabilities we must use "default" instead of nulls
- "Enable" storage migration for simulator hypervisor
- Remove restriction on "ClusterScopeStoragePoolAllocator" to find shared pools
Remove maven standard module (which only a few were using) and get ride of maven customization for the projects structure.
- moved all directories to src/main/java, src/main/resources, src/main/scripts, src/test/java, src/test/resources
- grep scan to search for src/com and src/org left over
- grep for <project>/scripts to fix pom.xml configuration
- remove custom <build> configuration in pom.xml
