Misc. agent cleanup and dead code deletion (#470)

* Fix path to agent::Agent in comment.

Otherwise `cargo doc` emits a rustdoc::broken_intra_doc_links warning.

* Use automatic link in comment for rustdoc.

Otherwise 'cargo doc' emits a warning.

* Delete checkpointer agent.

It is not used in current deployment.

* Delete kms-cli.

Not used in current deployment (no references).

* Include "--all" in precommit cargo fmt -- --check invocation.

* Delete unused and hidden src/bin programs.

These appear to have been introduced over a year ago and appear to be dead
code now.

Unhide them from vscode workspace too -- since they were hidden, automated
refactoring tools wouldn't find them until compiler failed.

* Update github CODEOWNERS to current Abacus team.

Drop optional authors field from Cargo.tomls.

* Drop processordb from .gitignore.

Processor crate has been deleted.

* Delete balance-exporter crate.

It is not used / no references.

* Hoist abacus-cli into its own top-level crate.

It is the only tool now, no reason to hide it inside
of a tools directory.

* Delete old relaese.sh, which only relates to Celo Optics.

* Cleanup top-level rust README.md.

-  Architecture paragraphs outdated, delete.
-  Point to run-locally.sh instead of documentation.

* Explain a bit more about crate deps in README.

* Dockerfile fix after tools directory restructuring.

We had previously hoisted abacus-cli out since it
was the only remaining tool.
