Support Deployment from Admin UI When Using Plugins

**Is your feature request related to a problem? Please describe.**
Added amplify video plugin to my app, which causes deployment fail when deploying from data modeling tab. I cannot edit my content until I deploy, however, causing a major problem. See awslabs/amplify-video#322 for original issue.

"Parameters: [secretPemArn, secretPem, publicKey, rPublicName, publicKeyName] must have values ."

```

**Describe the solution you'd like**
Successful deployment with added plugins.

**Describe alternatives you've considered**
Removing video plugin and using another means to serve video streams.

**Additional context**
Since the video streams need to be protected, this plugin is the best way to integrate video streaming into my app. I shouldn't have to lose my admin UI abilities because a plugin exists

Start by reproducing the failure from the Admin UI data modeling tab with the amplify-video plugin, using the recorded `amplify push --yes --allow-destructive-graphql-schema-updates` command and the CloudFormation error about missing parameters. Review awslabs/amplify-video#322 for plugin context. Done means an Admin UI deployment succeeds without removing the plugin.
