roachtest: metamorphically enable leader leases

[nvanbenschoten]

Part of #132762.

To increase test coverage of leader leases, this patch adds leader leases to the set of possible lease types when tests opt-in to metamorphic leases. As of fc68b0f, most roachtests do enable metamorphic leases, so this will provide good coverage of leader leases.

Before merging this, we should manually run all of these tests with leader leases to verify that they pass.

Release note: None

I ran a select collection of 18 roachtest which enable metamorphic leases and forced them to use leader leases. All passed on master (ef26d15).
