[Feature]: Add `block_until_done` arg to `remove_relation`

[sed-i]

Description

#665 added a block_until_done arg to remove_application.
It would be super handy to have the same for remove_relation.

python-libjuju/juju/application.py

Line 195 in 88eb6c4

async def destroy_relation(self, local_relation, remote_relation):

Urgency

It would save from a weird workaround

Code I'd Like to Run

await ops_test.model.applications[trfk.name].remove_relation(f"{ipr.name}:ingress", trfk.name, block_until_done=True)
# and then, without any additional `block_until`:
await ops_test.model.applications[trfk.name].add_relation(f"{ipr.name}:ingress", trfk.name)
