Fixes #7828

Tagging recently created instances can result in
InvalidInstanceID.NotFound errors.

By delaying the tagging until the last part of instance creation,
we should be typically more fortunate (avoiding all such race
conditions might need more work)

If no alias is passed one will now be created for you with the same name
as the target link container, as per the documentation

  - Added a more verbose response
  - includes its settable attributes and a list of its instances.
  - allows setting of tags, changes upon which mark the task changed
  - allow getting of information from asg module, not just setting
  - doesn't mark changed if the parameter wasn't specified
  - Availability Zones are pulled from the region

azure - fix for: temporary redirect, not deleted vhds, missing locations and role types, async api calls

For networks that have both a v4 and a v6 subnet, the floating IP plugin
currently has two problems:

* When determining the subnet for the provided `internal_network_name`, it
assumes that the first item in the list of subnets is the one you want.
Instead, it should pick the first v4 subnet.

* When multiple fixed IP's exist for a given port (as is the case in a network
a v4 and a v6 subnet), neutron needs a hint as to which fixed IP to associate
to the floating IP address (the v4 one).

* Fixed error messages to be more descriptive
* Removed direct use of subprocess module and replaced it with calls
  to module.run_command
* Changed AZURE_MANAGEMENT_CERT_PATH to be just AZURE_CERT_PATH, which
  matches what is expected by the inventory script
