The `clearknob` command clears the value that a knob has been set to in
the configuration database. Note that this does not mean the knob value
itself gets cleared - only the value in the configuration database is
cleared. The value of the knob will revert to whatever is hardcoded in
the corresponding `*Knobs.cpp` file.
Sample `fdbcli` session:
```
Welcome to the fdbcli. For help, type `help'.
fdb> getknob min_trace_severity
`min_trace_severity' is not found
fdb> setknob min_trace_severity 20
Please set a description for the change. Description must be non-empty
description: test
Committed (2)
fdb> getknob min_trace_severity
`min_trace_severity' is `20'
fdb> clearknob min_trace_severity
Please set a description for the change. Description must be non-empty
description: clear
Committed (4)
fdb> getknob min_trace_severity
`min_trace_severity' is not found
```
Transactions are also supported with the new `clearknob` command:
```
Welcome to the fdbcli. For help, type `help'.
fdb> begin
Transaction started
fdb> setknob min_trace_severity 20
fdb> clearknob min_trace_severity
fdb> commit
Please set a description for the change. Description must be non-empty.

If we restore a cluster and a previously created tenant was not included in the backup, then the tenant will be marked in an error state on the management cluster. It is then up to the operator to resolve the error, generally by deleting the tenant and recreating it if needed.
There is, however, the possibility that we restored a backup that was older than we wanted, and a newer backup would have the tenant. If we tried to restore the newer backup, it would not leave the previously missing tenant in a fully usable state.
We need to have a way to deal with this case. One option is to allow us to clear the error state of a tenant, and that can be performed before (or maybe even after) the second restore.

* cleanup
* adding assert false to disabled code
* list audits
* cancel audits and corresponding tests

* fix fdbcli audit_storage and fix CI issue
* fix fdb cli
* address comments
* fmt
* Added location_metadata fdbcli to query shard locations, assignements, numbers etc.
* Added `listshards` to get some random physical/non-physical shards.
* Resolved comments.
* Remove duplicate getRange() for DB handles and update existing GetRange to accept DB handles.
* Initial progress checkpoint on new ConsistencyScan role.
* Updated TODOs, finished most if not all state updates.
* placeholder
* Add more TODOs, documentation and comment improvements.
* Checkpoint round state to avoid advancing progress if commit fails.
* Bug fix, check is supposed to be for overlap, not lack of overlap.
* Added more TODO's and added faked read results / exceptions and faked DB size retrieval to prove the consistencyScanCore logic works.
* Update JSON schemas and command help.
* Add comment about lifetime stats reset.
* More TODO comments and some renames for clarity, some bug fixes.
* properly stopping consistency scan in simulation so that it doesn't run forever and cause quiet database to fail
* removing trailing comma from consistency_scan json schema
* Making CC inconsistency not an error if it's intentional tss corruption
* consistency scan actually reads storage locations
* added check that consistency scan actually completes a round in simulation, fixed bug and added debugging around consistency scan getting stuck
* made consistency scan properly fetch database size
* refactoring data check to be used in both consistency scan and consistency check
* checking that consistency scan always completes at least one round and doesn't get stuck
* cleanup
* fixing ide build
* consistencyscan fdbcli command wasn't actually changing db state
* consistencyscan fdbcli command always said enabled even when it wasn't
