enable CI in premium
Premium lacks CI at the moment.
tarball-internal has checks for premium on top of core. This sometimes results in failures for core MRs. See this Jenkins job as an example:
Line is too long (74), should be < 73 characters (tab is counted as 8 spaces).
Some of these checks are in core CI.
I suggest we enable the core CI checks in premium as well so that these collateral failures don't occur anymore.
I imagine this as pulling the latest tools from core and running them in premium.
