New Environment Item

What does this MR do and why?

As part of the new environment redesign, we want all of the environment actions and display to work via the local GraphQL state.

This beefs up a lot of the old components to make them work with GraphQL mutations and queries in a backwards compatible fashion.

How to set up and validate locally

Make sure to turn on the new_environments_table feature flag. On the GitLab repository, run:

cd ./bin 
./rails console
Feature.enable(:new_environments_table) //turns on the feature flag
Feature.disable(:new_environments_table) //turns off the feature flag, takes some time to kick in

Numbered steps to set up and validate the change are strongly suggested.
