New Enterprise Replicated Release Channel

[lucasvaltl]

Is your feature request related to a problem? Please describe

In order to improve our roll outs, we want to add another channel to replicated.

Describe the behaviour you'd like

• Create additional channel in replicated called enterprise
• Move existing customers to said channel in the replicated vendor portal (customers will only actually switch channel when they either update their license (see below) or update to a new version)
• Communicate with Cust Exp to ask these customers to update their license within replicated.
• Update license creation docs
• Update how to roll our self hosted internal docs
