Commit 2 : Integrates the CbfNode backend with the bdk's blockchain test framework.

Notes to Reviewers

The current CI tests won't work because nakamoto doesn't support our MSRV. Though you can run the modified tests in your local with toolchain 1.63 or higher.

Few of the tests are intermittently failing and needs further investigation. But overall this PR is ready for review of to be used for testing..

Thanks for all the help and support from @cloudhead and others who pitched in for various fixes in upstream.

Thanks @cloudhead for the review and suggestion.. It seems the structure of the crate has changed in recent master.. So I pinned the rev to 14902d3d5cc9442cdda82419f0f24277d86b243b. I couldn't find any release tag in github, and the published v0.3.0 in crates.io doesn't seem to include some latest fixes.. Anyway, this works for now, until we get a more stable release of nakamoto out in crates.io..

@thunderbiscuit this now includes AnyBlockhain and ConfigurableBlockchain updates..

@thunderbiscuit updated as suggested..

One more extra commit is added to disable to existing compact_filters logic, so we don't need to unnecessarily build rocksdb and other stuffs not used for nakamoto client..

Hey, we are in the process of releasing BDK 1.0, which will under the hood work quite differently from the current BDK. For this reason, I'm closing all the PRs that don't really apply anymore. If you think this is a mistake, feel free to rebase on master and re-open!
