What's in this PR?

Made Cadence metrics reporter services mutually exclusive.

Why?

From https://github.com/uber/cadence/pull/4180 multiple metrics reporters would cause an error on startup (see #1250 for more details).

Additional context

Decided to increment minor version due to the change being a breaking chart behavior change for configurations where both metrics reporter services are enabled.

Tested with the regular chart upgrade test.
