* Quick fix to stop containers in `run` script

* Pin GrafanaMatrix Dockerfile to old commit

The latest master has some changes in how the application is run. We don't
want to update just yet so we're pinning to an old commit.

* Make Compose files use a project directory

The main consequence of this change is that all paths have to be specified
from the root of the `deployments` folder. However, this makes it so that
we can reuse components in different deployments, like the GranfaMatrix
Dockerfile which is shared by all bridges.

* Use `project-directory` when stopping and updating network

If we don't use the full Compose command which includes `project-directory`
not all the containers get cleaned up correctly.

* Support multiple "best headers" from different forks

* Update the name of a test

* Add note about multiple scheduled changes

* Disallow multiple scheduled authority set changes

* Return multiple best headers from Runtime APIs

* Remove invalid test write-up

* Add some sketch-ups of test scenarios

* Clean up test scenarios

* Add module for testing forks

* Write headers to storage

* Add way to check expected outcome for header imports

* Add support for importing finality proofs

* Support importing headers which schedule changes

* Write out test scenario using new framework

* Map authority set changes across forks

Gets all the tests in the `forks` module passing

* Remove basic tests

These were used when working on the initial test helper

* Prevent multiple pending set changes on the same fork

* Remove old test which allowed imports past unfinalized header

* Ignore failing test (for now)

* Rewrite `if` comparison using `match` and `cmp`

Fixes Clippy warning: `comparison_chain`

* Add helper for writing test headers with default characteristics

* Fix test that checked authority set updates

* Make note about importing headers on different unfinalized fork

* Perform some cleanup on the fork module

* Fix Clippy complaints

* Provide list of unfinalized headers to Runtime APIs

* Add proofs to expect() calls

* Make tests the focus of the forks module

* Allow specific errors to be checked in fork tests

* Remove unused method

* Replace unreachable() statement with expect()

* Rename storage `unfinalized_headers() `to make its purpose more clear

* Update Runtime API name in relayer to match pallet

* Commit `unfinalized_headers` changes I forgot to add

* Rename ChainTipHeight to BestHeight

* Make schedule_next_set_change require a mutable reference

* Remove check for key when enacting authority set

We only expect to take the happy-path in the pallet anyways, so this check
to save ourselves the time spent decoding the entry isn't really used.

* Clear justification set when writing headers to storage

* Clarify why we only allow one set change per fork

* Change best_headers() to return HeaderIDs

Prevents us from returning full headers (which are more expensive to
get from storage) since we only care about header IDs (number, hash)
anyways.

* Fix Clippy complaint

* Make note about equivocations

* Use HeaderIds when returning incomplete headers

This change stops returning full headers which are more expensive
to get from storage than header Ids (number, hash) are. Clients likely
don't need the full header anyways which is why this change is fine.

* Introduce HeaderId type to reduce type complexity

* Add signal hash to storage during genesis config

* Return error instead of expect()-ing

* Fix Clippy lint about `ok_or` fn call

* Rename `forks` module to indicate that it's for testing

* Use `const` for `expect()` proofs

* Remove check that key exists before `kill`-ing value
