find the recovery version in the context of version vector. We will
need to extend the version vector recovery algorithm to do this
check in an efficient manner later.
the following ways:
- Make it use "max(KCV)", instead of "min(KCV)", as the default
recovery version
- Make it return the <max(KCV), recovery version> pair as output
- Make the invoker use the "max(KCV)" version returned by the
algorithm
- Address a bug related to the computation of recovery version (in
the case where a subset of log servers have empty
"unknownCommittedVersions" list)
And, make the invoker compute the max() and min() of recovery versions
of primary and satellite DCs based on the recovery versions computed
by the appropriate (with/without unicast) recovery version computation
algorithms.
* refactor management of cluster recovery version (crv)
- send the crv to tlogs as they rejoin cluster during recovery, not
just when an rv is computed.
- if a tlog has not yet received the crv, wait for it
* Propagate cluster recovery version to tlog for version vector recovery
Enable RECORD_RECOVER_AT_IN_CSTATE to store recovery version in cstate
* respond to review comments
* - dont sent rv to old tlog generations
- send crv after locking, if rv computed
* Remove CRV RPCs, have cursor pad beyond end tlog to RV
* Send end version in peek request to facility vv recovery
* Fix serialization in peek request interface.

* Add assertions to code paths with txsTag
txsTag should be obsolete by now, since it's used in 6.1, which is no longer
supported for upgrade.
* Actually remove txsTag usage

* Remove more code

* Disable two verbose trace events
They can cause TraceTooManyLines errors.
* refactor to use struct rather than tuple for uncommitedVersions
* Document UnknownCommittedVersions struct

The logic to determine the validity of a process joining a cluster now
belongs on the worker and the cluster controller. It is no longer
restricted to tlogs and storages, but instead applies to all processes
(even stateless ones).

* proof of concept
* use code-probe instead of test
* code probe working on gcc
* code probe implemented
* renamed TestProbe to CodeProbe
* fixed refactoring typo
* support filtered output
* print probes at end of simulation
* fix missed probes print
* fix deduplication
* Fix refactoring issues
* revert bad refactor
* make sure file paths are relative
* fix more wrong refactor changes
