As part of the Support Priority1 and CEO
OKR epic Allow existing Premium customers to
trial Ultimate, this MR introduces a new

of what was started by !135759.
The new plan should behave the same way as the
regular Ultimate plan, without any of the i
limitations imposed by the current trial experience i
intended for non-paying customers.
