Fixes trove create output

Reasons:
- When using trove create, the output for create instance shows all
  unwanted information as described in bug, like flavor details
  and datastore as a dict.

Changes:
- Moved the configuration attribute setting to top before setting up
  any other attribute.

Get rid of XML related trove client bindings

We will no longer support XML for the trove API; it behooves us to
remove XML related code, and clean up the trove client.

Fix database-list via CLI for large # of dbs

When an instance contains more than 20 databases, only the last n-20 were being
shown when trove database-list was run. The do_database_list method wasn't
correctly tracking the output when multiple pages were present.

Fix create call for security group rules

Reasons:
 - The security group rule create call was expecting
   from_port, to_port, and protocol as arguments, but
   the Trove API was ignoring these since it picks these
   up from the respective datastore confs.

Changes:
 - Removing the extra arguments from the security-group-rule
   create command:
   - from_port
   - to_port
   - protocol

Note that even though the user was able to specify the ports
for the rule these were _never_ being honored since these
were being picked up from the respective config files.

Usage before change:
 - trove secgroup-add-rule <security_group> <protocol>
                           <from_port> <to_port> <cidr>

Usage after change:
 - trove secgroup-add-rule <security_group> <cidr>
