Fix sidekiq-cluster name selector with colons

See merge request gitlab-org/gitlab!25910

This has been replaced by Labkit::Tracing and is now contained in the
labkit gem.

This is now contained in the labkit middleware.

This updates Labkit-ruby to 0.10.0, which allows us to remove the
separate middleware for tracing and rely on the single middlewares for
sidekiq in labkit.

Allow selecting a group to apply license to

See merge request gitlab-org/gitlab!25124

A queue name can have colons (to separate it from its namespace). This
wasn't part of the term regex so trying to select a queue by name, when
the name contained a colon, would fail.

This also allows every other predicate to accept colons. Although none
of them strictly need to, it doesn't harm them: feature categories and
resource boundaries can't contain colons anyway, and colons weren't part
of the general syntax.
