Dinesh Bhor d45f754cbb Add reserved_host to failed_host's aggregate
Reserved hosts can be shared between multiple host_aggregates. So
before evacuating the instances from failed_host to reserved_host,
the target resered_host should be added to the same aggregate in
which the failed_host is.

This patch adds the reserved_host to failed_host's aggregate.
Adding reserved_host to aggregate is optional and can be configured
by operators with the help of new configuration parameter
'add_reserved_host_to_aggregate' which is added under the 'host_failure'
section. This config option defaults to 'False'.

'add_reserved_host_to_aggregate' whether to add or not a reserved_host
to all host aggregates which failed compute host belongs to.
To use this feature, following config option need to be set under
``host_failure`` section in 'masakari.conf' file::
