Adds includedir back to templates

This adds includedir to the mysql templates, which allows overriding of
default my.cnf settings. Additionally, /etc/mysql/conf.d is created if it
doesn't already exist to prevent mysql from failing.

Implement resize volume method

Trove use Cinder as volume backend default and Cinder requires that volume must
in "available" status if wish to resize. So we should stop db firstly, then
detach volume from instance and resize volume. Finally, restart db in ease.

If resize volume failed, the instance may stuck into "RESIZE" status. Because
we have no idea to rescue the volume which is in "error_extending" by Cinder.

Support Security Group Name Prefix Customization

As of now, if CONF.trove_security_groups_support == True, then a
Security Group is created for every new Instance, following the
naming scheme of: "SecGroup_<Instance's UUID>".

Nicira NVP for Quantum enforces a Security Group naming limitation of
40 chars maximum. Given the UUID's length, this only leaves 2
characters for the prefix, e.g. 'SG' vs. 'SecGroup'.

Even in lieu of restrictions, it's not inconceivable that a
vendor/user might want to customize the naming scheme of their
Security Groups to align with other cloud providers, etc.

service_statuses updated_at Field Not Set

The service_statuses updated_at value is never set due to
inconsistent column naming ('updated' is automatically set in the
base model). The result is the value remains NULL throughout the
instance creation lifecycle, despite multiple row updates.

Fix: override save() and set updated_at (following the pattern
established in agent_heartbeats)
