feat: ✨ Added Lifecycle Hook and Termination Grace Period

[danielcrisap]

• Adding Lifecycle Hook
• Added Termination Grace Period

Those features are intended to achieve the Graceful shutdown from Trino Worker nodes.
https://trino.io/docs/current/admin/graceful-shutdown.html#admin-graceful-shutdown

With lifecycle hooks, when the pods receive a SIGTERM will request the API to start the SHUTTING_DOWN state and the terminationGracePeriodSeconds is for K8s waiting for this process to be concluded.

+1 for this feature.

Would be a nice feature to have on the coordinator as well. I can branch this PR and create another one since I'm unsure when the CLA will be signed.

Sorry for the delay,

I've sent the email with the CLA signed; I will wait a few days to recheck.

[tbaeg]

@danielcrisap Any chance you could also add these to the coordinator?

I included the coordinator; I just removed the example because, in the Trino doc, this API is only for Worker nodes.

Trino has a graceful shutdown API that can be used exclusively on workers in order to ensure that they terminate without affecting running queries, given a sufficient grace period.

Well.. there is a graceful shutdown for coordinator in the works...

Awesome, thank you! Yeah, mostly looking for the lifecycle option as it provides flexibility for some custom operations to be executed. Appreciate you including it!

@tbaeg and @mosabua ,
Do you think we can include this feature in the next release?

[tbaeg]

No issues from me but I also have no decision making authority. :)

[mosabua]

@radek-starburst @losipiuk @nineinchnick .. any chance you could look at this?

I don't have merge permission, so I can't set to use the squad strategy for merging into main.
