chore: remove unused odigos config controller (#2177)

The controller for the instrumentation config was needed for old
language detection which was triggered from instrumentor.

New language detection will be triggered once when the instrumentation
config is first created, and use whatever values are in the config at
this time.

Hence this controller can be removed
