Trove/add-configuration-copy-command

Description

This enhancement is to add a new "configuration-copy" command.

Justification/Benefits

Creating a configuration group from the CLI is complicated and error prone due to entering values as a JSON formatted string.

In many situations the user will want to have multiple 'similar' but slightly different configuration groups - so being able to copy an existing group and then tweak it will save time and frustration.

CLI interface

The configuration-copy command will perform the following operations.

1. Use the existing _get() method to obtain the source configuration.
2. The body of the new configuration will be initialized with the source configuration values, datastore type and datastore version.along with the new configuration name and description.
3. The body will passed to the existing _create() method to create the new configuration.
4. The new configuration will be returned to the caller.

An example of the usage follows:

vbox@vmw-1:~/dev/trove-integration/scripts$ trove configuration-copy 03511d07-3865-4501-9e08-98b39facd9b1 testconfig2 --description "A new description"
