Retrieving templates with inner join on host table was turning out to be
more expensive than finding distinct hypervisor types for a zone using
hsot table and then finding templates for those types

Added caching for ConfigKey value retrievals based on the Caffeine
in-memory caching library.

Currently, expire time for a cache is 1 minute and each update of the
config key invalidates the cache.

* Updated charset to utf8mb4, for display_name column/user_vm table and job_result column/async_job table to support unicode chars & emojis
* Added API arg validator for RFC compliance domain name, to validate VM's host name
* Updated user resources name / display name column's charset to utf8mb4
* Check and update char set for affinity group name to utf8mb4, from the data migration in upgrade path
* Updated backup offering name column charset to utf8mb4
* Added unit tests for vm host/domain name validation
* Added smoke test to check resource name for vm, volume, service & disk offering, template, iso, account(first/lastname)
* Updated resource annotation charset to utf8mb4

* Mitigation for non-scalable Powerflex/ScaleIO clients
- Added ScaleIOSDCManager to manage SDC connections, checks clients limit, prepare and unprepare SDC on the hosts.
- Added commands for prepare and unprepare storage clients to prepare/start and stop SDC service respectively on the hosts.
- Introduced config 'storage.pool.connected.clients.limit' at storage level for client limits, currently support for Powerflex only.
* tests issue fixed
* refactor / improvements
* lock with powerflex systemid while checking connections limit
* updated powerflex systemid lock to hold till sdc preparation
* Added custom stats support for storage pool, through listStoragePools API
* code improvements, and unit tests
* Update config 'storage.pool.connected.clients.limit' to dynamic, and some improvements
* Stop SDC on host after migration if no volumes mapped to host
* Wait for SDC to connect after scini service start, and some log improvements
* Do not throw exception (log it) when SDC is not connected while revoking access for the powerflex volume
* some log improvements
