Updated Avi Modules with new features and documentation update.

[grastogi23]

SUMMARY

1. Support to perform patch operation using the modules. The data update method is
   selected using avi_api_update_method=patch and patch operation is determined by
   avi_api_patch_op. The patch data is the normal params that are provided in the modules

2. Support for avi_credentials as single authentication dictionary for all API calls.
   This is preferred way as opposed to previously all credentials details would pollute
   the individual Ansible tasks. It also allows the module development to be enhanced
   without breaking compatibility for new authentication schemes like SAML etc.

3. Support for sharing api_context between the module invocations. This is a
   workaround to not do multiple logins to Avi Controller and be able to
   re-use single login across multiple REST API calls.

4. Documentation update for new parameters and existing ones with Units data.
