When a configuration K/V pair is modified, always output the K/V pair values
...
With this patch, if there is a configuration special key in the
database, even if the value is reverted to default/hidden, it will still
be forwarded when constructing a JSON string. This should address the
requirements described in https://github.com/apple/foundationdb/issues/3551 .

backup_worker_enabled flag is set for 7.0 version.

The default is to enable new backup workers. Users can disable this flag to
turn off the backup worker feature.

Add a DB configuration option for backup workers
...
Right now, the default is to keep the old backup behavior, i.e., do NOT use
backup workers. Specifically, if BackupType is not set (or is set to default),
the master will not recruit backup workers and will not add pseudo locality for
backup workers.
The StartFullBackupTaskFunc is updated to check if backup worker is enabled.
Only when it is not enabled, starting a backup will wait on all backup workers
to be started.

removed LocalitySetRef and IRepPolicyRef typedefs, because for clarity the Ref suffix is reserved for arena allocated objects instead of reference counted objects.

Implement log_version.
...
This mega-commit introduces a new configuration setting, `log_version`,
that controls the TLog implementations and features that are available
within FDB, so that users can opt in to new features if they're willing
to sacrifice backwards compatibility.

fix: forced recoveries now require a target dcid which will become the new primary location. During the forced recovery, the configuration will be changed to make that location primary, and usable_regions will be set to 1. If the target dcid is already the primary location, the forced recovery will do nothing. This makes forced recoveries idempotent, so it is safe to the client to re-send forced recovery commands to the cluster controller.
...
fix: the cluster controller attempts to do a commit to determine if the cluster is alive, since its own internal recoveryState might not be up-to-date.
fix: forceMasterFailure on the cluster controller did not always cause the current master to be re-recruited
