Trove depends on MySQL-python package, to compile and install it is
required libmysqlclient-dev, otherwise the installation procedure
described in 'doc/source/dev/manual_install.rst' will fail in recently
installed boxes.

mgmt show/get call in addition to volume.used.

This will help in validating cinder volume size reflects actual
filesystem size.

Using base32 encoding to generate DNS records

The Designate driver generate record names by
hashing and 64-base encoding the instance ID.
The problem is that 64-base encoding can generate
hyphens and upper/lower case letters. Hyphens are
illegal when it is at the beginning of the name.
Name is also case insensitive. So the best solution
is to use BASE-32 encoding.

Make use of IP filtering when creating DNS records

Previously, the return list from get_ip_address in
trove.instance.views was not filtering by the CONF.ip_regex.
(See blueprint add-ip-addr-filter-to-instance-view for more
information). DNS uses this method to get the IP. Therefore
it was not creating record with the right IP. Moving the filtering
logic to the get_ip_address method will ensure that both DNS and
instance view will obtain the right IP.

Log service_status.status instead of service_status
