Remove config druid.coordinator.compaction.skipLockedIntervals

[kfaraz]

Description

The default of the config druid.coordinator.compaction.skipLockedIntervals has been true for many releases and has been working as expected. There is no case in which we would want this to be false anyway.

Release note

The config druid.coordinator.compaction.skipLockedIntervals is being removed as it has been tested thoroughly and should always be true.
