Support Prism Central category mapping for ansible groups

[engin]

Hello,

This PR adds support to retrieve Prism Central Category mapping to Ansible inventory group.

• Define inventory plugin variable group_category default ansible_group
• Create category in Prism Central and assign possible group names
• Configure VM categories using previously created group values

@engin , we have ansible constructed inventory feature patch going in next release ( #233 ). This will enable creation of custom groups based on expressions/conditions on vm information.

The use case of groups based on category and vm name can be achieved using constructed inventory feature given we have category and vm name in vm information for which created a new issue (ref. #274 ). Can you make changes as per that ?

For example, using ansible constructed inventory:

groups:
       category_based_group: "test" in category_mapping

groups:
       vm_name_based_group: "test" in name
