The change feed metadata mutations use \xff\x02/feed/ prefix, which was not
considered as "metadata mutations", thus not sent to the resolvers. This makes
the private mutation generation not possible for change feed if the knob
PROXY_USE_RESOLVER_PRIVATE_MUTATIONS is on. Fix by making it a metadata
mutation.
Need to be careful what values applyMetadataMutation needs.
Need to call txnStateStore->enableSnapshot() after receiving the broadcast to
allow semiCommit to happen.
Not only can we now compile this giant code block in parallel with the
rest of the code, we also no longer compile this giant function twice!
(Once for the master, once for the proxy.)
The usedIds is updated by master registration request, which populates the
usedIds map. However, this request may contain processes that cluster controller
is not aware, i.e., not in id_worker map.
This is ok until I added tracing the usedIds, which silently insert an empty
entry into id_worker map for the unknown process. This new entry can cause
crashing failure when trying to access its LocalityData.
Remove AsyncTrigger for usedIds, and change to serverInfo->onChange.
Use const & to avoid unnecessary copies in WorkerInterface's LocalityData
and getExtraTLogEligibleMachines().
* Rename Optional/ErrorOr cast_to to castTo.
* Make printable(Optional<T>) templated rather than restricted to StringRef types.
* Fixes bug in (unused) ErrorOr.castTo where an ErrorOr that was not set would lose its error.
Remove the use of relative paths. A header at foo/bar.h could be included by
files under foo/ with "bar.h", but would be included everywhere else as
"foo/bar.h". Adjust so that every include references such a header with the
latter form.

* Detail names now all start with an uppercase character and contain no underscores. Ideally these should be head-first camel case, though that was harder to check.
* Type names have the same rules, except they allow one underscore (to support a usage pattern Context_Type). The first character after the underscore is also uppercase.
* Use seconds instead of milliseconds in details.
Added a check when events are logged in simulation that logs a message to stderr if the first two rules above aren't followed.
This probably doesn't address every instance of the above problems, but all of the events I was able to hit in simulation pass the check.
