Borgmatic

* 276, 285: Disable colored output when "--json" flag is used, so as to produce valid JSON output.
* After a backup of a database dump in directory format, properly remove the dump directory.
* In "borgmatic --help", don't expand $HOME in listing of default "--config" paths.

* 268: Override particular configuration options from the command-line via "--override" flag. See
the documentation for more information:
https://torsion.org/borgmatic/docs/how-to/make-per-application-backups/#configuration-overrides
* 270: Only trigger "on_error" hooks and monitoring failures for "prune", "create", and "check"
actions, and not for other actions.
* When pruning with verbosity level 1, list pruned and kept archives. Previously, this information
was only shown at verbosity level 2.

* Fix repository probing during "borgmatic init" to respect verbosity flag and remote_path option.
* 249: Update Healthchecks/Cronitor/Cronhub monitoring integrations to fire for "check" and
"prune" actions, not just "create".

* 259: Optionally change the internal database dump path via "borgmatic_source_directory" option
in location configuration section.
* 271: Support piping "borgmatic list" output to grep by logging certain log levels to console
stdout and others to stderr.
* Retain colored output when piping or redirecting in an interactive terminal.
* Add end-to-end tests for database dump and restore. These are run on developer machines with
Docker Compose for approximate parity with continuous integration tests.

* Fix "--repository" flag to accept relative paths.
* Fix "borgmatic umount" so it only runs Borg once instead of once per repository / configuration
file.
* 253: Mount whole repositories via "borgmatic mount" without any "--archive" flag.
* 269: Filter listed paths via "borgmatic list --path" flag.

* 235: Pass extra options directly to particular Borg commands, handy for Borg options that
borgmatic does not yet support natively. Use "extra_borg_options" in the storage configuration
section.
* 266: Attempt to repair any inconsistencies found during a consistency check via
"borgmatic check --repair" flag.
