Description

What problem does the new feature solve?

Currently I don't see an option to host greptimedb on a subpath.

For example, I configure my ingress to match example.com/monitoring/greptimedb and open example.com/monitoring/greptimedb/dashboard in my browser, I'll be redirected to example.com/dashboard which does not exist.

What does the feature do?

The feature will introduce a new subpath argument / config parameter where users can define the subpath they want to host greptimedb on.

Default will be / which means that we would have no breaking changes.

Implementation challenges

None - should be straight forward.
