EPIC: Add Environment administrative action to React

# What is currently missing?

Coral does not currently support administrative access operations for the administors on environments.
# How could this be improved?

Add a new clean design to coral to allow certain administrative users to execute administrative actions.
Actions: Adding a new Environment (Kafka, Schema Registry, Kafka Connect)
Connect to the created clusters
Allow schema registries to be connected to Kafka environments
Form Validation
Offer example tenant config to add new environment to the topic request drop downs.
You can delete an environment whenever you want (as long as you are an administrator)

# Is this a feature you would work on yourself?

- [ ] I plan to open a pull request for this feature
