Only fetch requested worker interfaces in rebootWorkerActor
Add killall test to multiprocess_fdbcli_tests
Make the rebootWorker only sends requests if all the requested workers are valid
Add comments; Organize print texts; Fix the bug clear the map every time run kill/suspend/expensive_data_check
Currently, GlobalConfig is a singleton that means for each process there is only
one GlobalConfig object. This is bug from clients perspective as a client can
keep connections to several databases. This patch tracks GlobalConfig for each
database using an unordered_map in flowGlobals.
We discovered this bug while testing multi-version client, where the client got
stuck. This was lucky, as normally it'd just write down config to the wrong
database.
* Re-throw operation_cancelled
There's a few places in fdbcli where we don't rethrow operation
cancelled but wait on a future. It's very unusual that you don't want to
rethrow operation_cancelled.
* Update ASSERT
It's possible to get error_code_broken_promise here if the network has
already shutdown.
* Initialize cluster version at wall-clock time
Previously, new clusters would begin at version 0. After this change,
clusters will initialize at a version matching wall-clock time. Instead
of using the Unix epoch (or Windows epoch), FDB clusters will use a new
epoch, defaulting to January 1, 2010, 01:00:00+00:00. In the future,
this base epoch will be modifiable through fdbcli, allowing
administrators to advance the cluster version.
Basing the version off of time allows different FDB clusters to share
data without running into version issues.
* Send version epoch to master
* Cleanup
* Update fdbserver/storageserver.actor.cpp

* Jump directly to expected version if possible
* Fix initial version issue on storage servers
* Add random recovery offset to start version in simulation
* Type fixes
* Disable reference time by default
Enable on a cluster using the fdbcli command `versionepoch add 0`.
* Use correct recoveryTransactionVersion when recovering
* Allow version epoch to be adjusted forwards (to decrease the version)
* Set version epoch in simulation
* Add quiet database check to ensure small version offset
* Fix initial version issue on storage servers
* Disable reference time by default
Enable on a cluster using the fdbcli command `versionepoch add 0`.
* Add fdbcli command to read/write version epoch
* Cause recovery when version epoch is set
* Handle optional version epoch key
* Add ability to clear the version epoch
This causes version advancement to revert to the old methodology whereas
versions attempt to advance by about a million versions per second,
instead of trying to match the clock.
* Update transaction access
* Modify version epoch to use microseconds instead of seconds
* Modify fdbcli version target API
Move commands from `versionepoch` to `targetversion` top level command.
* Add fdbcli tests for
* Temporarily disable targetversion cli tests
* Fix version epoch fetch issue
* Fix Arena issue
* Reduce max version jump in simulation to 1,000,000
* Rework fdbcli API
It now requires two commands to fully switch a cluster to using the
version epoch. First, enable the version epoch with `versionepoch
enable` or `versionepoch set <versionepoch>`. At this point, versions
will be given out at a faster or slower rate in an attempt to reach the
expected version. Then, run `versionepoch commit` to perform a one time
jump to the expected version. This is essentially irreversible.
* Temporarily disable old targetversion tests
* Cleanup
* Move version epoch buggify to sequencer
This will cause some issues with the QuietDatabase check for the version
offset - namely, it won't do anything, since the version epoch is not
being written to the txnStateStore in simulation. This will get fixed in
the future.

Changing `memory` option to limit resident memory instead of virtual memory, in config file and fdbserver/fdbbackup/fdbcli command-line argument. Since `rlimit` doesn't support limiting virtual memory, the current implementation have both of fdbmonitor and the fdbserver/fdbbackup process checking process RSS periodically and kill and restart the process if the limit is exceeded.
Adding a new `memory_vsize` option to limit virtual memory, if backward-compatible behavior is desired.

MacOS warnings are format warnings, e.g., `format specifies type 'long' but the argument has type 'Version' (aka 'long long')`.
Windows warnings are `ACTOR does not contain a wait() statement`.
