The banishment of Address

[cloutiertyler]

Description of Changes

Jeff and I worked on Friday to remove all uses of Address as an identifier for a database. Address is still used for what will eventually become ConnectionId.

There is a corresponding private PR.

API and ABI breaking changes

This breaks the CLI API as well as the HTTP and WebSocket APIs. It also edits the system tables.

Expected complexity level and risk

4

This complexity rating applies not only to the complexity apparent in the diff,
but also to its interactions with existing and future code.

This impacts many APIs as mentioned above. The change is mostly mechanical, but not entirely.

Testing

Describe any testing you've done, and any testing you'd like your reviewers to do,
so that you're confident that all the changes work as expected!

• We have run the unit tests and smoke tests.

lFYI this could conflict and/or get good help from #1876, in special everywhere we pass Address and/or ExecutionContext it will removed it in #1876, ie I several of the same lines doing that refactor.

Trusting kim, just in case I somehow wound up as a code owner on this. I have not actually reviewed this PR, but Kim's review satisfies me.

[jdetter]

I have not tested this but I've reviewed the files I'm a code-owner of. I left one follow-up note for Zeke but these changes look correct to me.

Although I am a partial author of this, I just want to so that this one looks good to me.
