CLI: Add functionality to operate on Workspace Membership

[rajdip-b]

Description

We would like to perform the following operations for workspace membership using our CLI:

• Transfer the ownership of the workspace to another user (keyshade workspace membership transfer-ownership <workspace-slug> <new-owner-email>)
• Invite a user to a workspace (keyshade workspace membership invite <workspace-slug> <invitee-email> <space separated role slugs>)
• Remove a user from a workspace (keyshade workspace membership remove <workspace-slug> <user-email>)
• Update the role of a specific member (keyshade workspace membership update-role <workspace-slug> <user-emails> <space separated role slugs>)
• Accept invitation (keyshade workspace membership accept-invitation <workspace-slug>)
• Decline invitation (keyshade workspace membership decline-invitation <workspace-slug>)
• Cancel invitation sent to a user (keyshade workspace membership cancel-invitation <workspace-slug> <invitee-email>)
• Leave workspace (keyshade workspace membership leave <workspace-slug>)
• Get all members of a workspace (keyshade workspace membership list <workspace-slug>)

Solution

• Create a new file named membership.workspace.ts under apps/cli/src/workspace
• Create an implementation of command.interface.ts and name it WorkspaceMembershipCommand
• Add this command in the command list of workspace.command.ts
• Stash all the functions in src/commands/workspace/membership.
• Use the workspaceMembershipController under ControllerInstance to make the API calls.
• Use the controller in here to make the API calls.
