drop namespace annotations

[phoracek]

What this PR does / why we need it:

Fixing BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1847594

We should not sneak into the restricted space.

Special notes for your reviewer:

Release note:

Drop runtime level label from Namespace

[RamLavi]

@phoracek
right now it's ok to insert this because there is no way KMP would try to allocate its own pods since their namespace in not opted in.
But we need to come up with another way to do that should we remove the opt-in feature in the future.

[phoracek]

We can rollback to what we used to do before this label. We had our own that we placed on our namepsace and used it for the anti-selector.

@RamLavi there was some reformatting introduced in a previous PR. Weird that it passed. Should be fixed now.
