Add VSS Store CI Integ Test

[G8XSU]

• Pulls and runs vss-server
• Runs kvstore testcases against local hosted instance of vss-server.

Depends on #158

Thanks! Do we see a way to integrate it more closely? In particular, we should run channel_full_cycle against the VssClient backend and see that it works. Note that to that end I'll introduce a TestSyncStore that wraps all provided backends and asserts they behave identically (76d2f03). This is currently part of #159, but will be included as part of the upgrade to 0.0.117. We'll also want to add VssStore as part of that and run tests against all of these backends to be sure.

Note that we'll want to run the usual tests against this backend, so while it might be a bit cleaner to have a separate CI worflow, we'll probably need to do this setup as part of our 'regular' CI run, possibly as part of a vss feature flag for now.

[G8XSU]

I think we can do this setup in separate workflow and run all tests against it.

I didn't want to bloat single ci workflow so much and wanted to maintain some separation of concerns regarding vss-integration in particular .

Yes, once we have a public api to build with vss, will add that.

There is no reason to wait for the public API, as we can just use build_with_store.

That test is now part of #158 , so that it is tested as part of this same ci

Rebased on #158 and #151

Depends on lightningdevkit/vss-server#25
to fix CI failure, rest should be good

This needs a rebase now that #158 landed :)

Rebased on #158

Rebased on #158

The integration test fails due to:

thread 'test::functional_tests::channel_full_cycle_with_vss_store' panicked at src/test/functional_tests.rs:31:92:
called `Result::unwrap()` on an `Err` value: ReadFailed

I.e., on build_with_vss_store:

[G8XSU]

I think this will be fixed once latest vss-client is published(since it depends on some changes in that), i will verify it once.

[G8XSU]

Depends on #213 for now.

Depends on #213 for now.

Needs a rebase now that #213 has been merged.

[G8XSU]

@tnull rebased and that error is fixed now.

LGTM.

As discussed elsewhere, I'd eventually like to collect all the integration tests under ./tests, but that can happen in the future.
