feat: version blocking for CLI

[attilah]

Description of changes

This PR adds a version blocking functionality to the CLI to guard against unwanted or unexpected results when a modification (add, remove, push, etc) operation would be executed against a project that was already pushed by a newer version of the CLI.

From now on Amplify CLI defines a minimumCLIVersion in its package.json file and also emits the same information into the root stack's Metadata section.

The version of the CLI that was used to execute the last push operation, also added to the root stack's Metadata and as a Tag on the stack resources as well.

If the CLI after checking the versions determine that the currently running CLI version has a lower version number it will exit the process.

There are certain commands that does not enforce this version check like amplify version or amplify env list.

If the version check should be bypassed for some reason, defining the AMPLIFY_CLI_DISABLE_VERSION_CHECK environment variable with any value will enable this.
