[Feature Request] Worker Slot & Polling Auto-Tuning

[Quinn-With-Two-Ns]

Is your feature request related to a problem? Please describe.

Temporal worker should be able to auto configure themselves to maximize resource utilization. The exact design still needs to be ironed out.

Worker/Activity Pollers:

• [ ] Go - https://github.com/temporalio/sdk-go/issues/1322
• [ ] Java - https://github.com/temporalio/sdk-java/issues/1956
• [ ] Core - https://github.com/temporalio/sdk-core/issues/662
• [ ] TypeScript - TODO after core
• [ ] Python - TODO after core
• [ ] .NET - TODO after core

Had a discussion with Marcelo and @tsurdilo earlier this week, where they indicated that this is quite a pain point for customers—dev-success folks are having to help out a lot with tuning, and having differences in behavior/semantics across different SDKs (e.g. core-based vs. Java/Go) is only making things harder.

Whups my bad, I missed that this was about pollers AND slots. Reopening.
