User metadata and workflow metadata query

[cretz]

Describe the solution you'd like

Users need to provide certain bits of user metadata that is visible in the UI/CLI. Specifically from a user POV we will start out with:

• Fixed "static summary" and "static details" on workflow start (includes signal with start and child workflow and scheduled workflows)
• Updateable-within-workflow "current details" string
• Workflow metadata query that includes "current details" above and, if available, information about registered signals/queries/updates
• "summary" on timer start (can serve as "timer ID")
• "summary" on activity

The text format of summary/description is TBD (probably some form of mini markdown). More metadata may be added in the future.

@cretz Is this issue a duplicate of https://github.com/temporalio/features/issues/51?

[cretz]

Yes, I think it basically is (or rather this includes that).
