The metacluster status command in fdbcli currently reports some useful metacluster information when run on a
management cluster. We should update this command to report a status even on data clusters of a metacluster and
standalone clusters that do not belong to any metacluster.
- On data clusters, this would report that the cluster is a data cluster as well its name and the name of the metacluster it is a part of.
- On standalone clusters, status should report that the cluster is not part of a metacluster.
Test plan:
- CI
- Manual test
- Added new test `metacluster_fdbcli_tests.py` that can be run with ctest `ctest -R metacluster_fdbcli_tests`
* 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.

Up unto here this code is only very rudiemantery tested.
This is a firest attempt of making cpack more user-friendly.
The basic idea is to generate a component for package type so
that we can have different paths depending on whether we build
an RPM, a DEB, a TGZ, or a MacOS installer. The cpack package
config file will then chose the correct components to use.
In a later point this should make it possible to build these
with `make packages` and the ugly iteration with calling cmake
between each package would be obsolete. While this solution is
a bit more bloated, it is also much more flexible and it will be
much easier to use.
Another benefit is, that this will get rid of all warnings during
a cpack run
