Activate Collator Offline Feature in Moonbeam

This proposal is to quickly activate the collator offline/kick feature on the Moonbeam network. This feature was introduced in RT2600 but not activated.

The main intent of activating this feature is to ensure that collators upgrade their client to v0.38.0 to meet the requirements to support RT3000 going live July 8th 2024. The RT3000 brings significant changes and enhancements to the Moonbeam network and it is critical all active collators are ready to support this upgrade.
