Set postgresql max_connections=200

Browse Source 
Now that we have multiple workers running by default
in various projects (nova/cinder/glance/trove), the
postgresql job is failing intermittently with connection
failures to the database.

The default max_connections for postgresql is 100 so here
we double that.

Note that the default max_connections for mysql used to
be 100 but is now 151, so this change brings the postgresql
configuration more in line with mysql.
