[amolina-adobe]

Description

Removes all references to the legacy (MGQL) mesh from the CLI plugin command output.

Affects the following commands:

• create
• describe
• status
• delete

Includes:

1. removal the legacy mesh url
2. removal of legacy mesh statuses
3. removal of any migration notices
4. removal of api key creation, subscription, and deletion
5. re-labeling of "Edge mesh" to "Mesh" as it is the sole output
6. minor updates to various command messaging

Motivation and Context

Coerce customers to migrate to edge mesh in production, due to complete deprecation of the legacy mesh (MGQL).

How Has This Been Tested?

• Verified unit tests pass
• Verified CLI tests pass after updating them to account for new messaging
• Manual testing of all commands
• Verified absence or errors in Dev Console UI when creating a mesh with new plugin (without an API Key)
• Verified rolling back to an old version of the plugin still works with a mesh created the new plugin (without an API Key)
