EWC/Enterprise transition to OpenSource

[arm4b]

Currently Ansible deployment provides functionality of installing EWC/Enterprise version.
There is a dedicated role for that: https://github.com/StackStorm/ansible-st2/tree/master/roles/StackStorm.ewc

As Extreme Networks open-sourced the EWC Enterprise (https://stackstorm.com/2020/05/27/extreme-networks-donates-ewc-to-linux-foundation/), remove the Enterprise functionality from the Ansible module. Rework the module so the settings like RBAC/LDAP could be still easily adjusted via st2 role.

This could be done once the Enterprise functionality is integrated into core StackStorm code.

From discussion on the November TSC meeting then RBAC would be disabled by default to ease upgrade for community users, but would need an option to enable as a parameter (to replace the licensekey parameter)

👍

Looking at the current Ansible variables config, I guess something along the lines:

st2_rbac:
  enable: yes
  roles: ...
  assignments: ...

or st2_rbac_enable: yes. Same for ldap.

Which will change the respective st2.conf settings.
