Juan Antonio Osorio Robles 71b6c8c5f7 Use newer configuration options for libvirt's live migration URI
The live_migration_uri option that was being used in case TLS is used in
live migration doesn't permit the usage of a host other than the one
detected automatically by nova. This is problematic for cases like TLS
where the address needs to match the certificate's SubjectAltName entry.
So instead, this patch takes into use the two recommended options:

* live_migration_inbound_addr
* live_migration_scheme

These will be used by nova to determine the URI.

On the other hand, libvirt_migration_uri is set to be deprecated at some
point. But, a way to add the query parameters to the query is
needed before this happens.

features:
- The paremeter 'live_migration_inbound_addr' was introduced to the libvirt
live migration module. This sets the configuration option with the same
name in the nova configuration, in the 'libvirt' section.
- If TLS is enabled for libvirt's live migration, the module will set the
configuration option named 'live_migration_scheme' in the 'libvirt' section
to have the value 'tls'. This will be used by nova to form the scheme for
the live migration URI, e.g. 'qemu+tls://...'.
- Note that the usage of 'live_migratin_inbound_addr' doesn't permit adding
extra parameters to the live migration URI as of the writing of this.
