COMPLETES # SPARK-486926

This pull request addresses

The need to be able to reclaim the host role by any other participant in the meeting. This is especially useful in meetings where hosts of the meeting don't join and one of the guests has to take up the role of a host.

Refer #3272 and #3289 for the same functionality being added in the beta branch. This needed to be done in the master branch due to the release of USM.

Confluence document for reclaiming host.

by making the following changes

1. Added the types required in members for the ServerRoleShape
2. Added utility functions to create the required role object in the body from a member's parameters
3. Added the assignRoles function to the members object which eventually triggers the request to assign caller as Host.

Change Type

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update
• Tooling change
• Internal code refactor

The following scenarios where tested

1. Started a meeting using API
2. Joined the meeting using the host on Webex desktop app
3. Created a guest user and token. Joined the same meeting in Step 1 using this guest
4. Triggered the new reclaim function using a button on the kitchen sink app along with the guest user's participant ID and hostKey. The desktop app now reflected the guest user as the host.
5. Transferred host back to the original host of the meeting (desktop app)
6. Triggered the reclaim action again using the kitchen sink page. Checked if the guest user was made host again.
