* create virtual file as PROXMOX/... instead of /var/lib/... so it
  cannot clash with regular files
* allow setting the restore path using "restore_path" option
* adapt systemtest

* switch backup/restore branch based on self.level
* ignore restoretodisk on backup

* functions that should never be called throw NotImplementedError
* add get_acl() / get_xattr() that return no data

Retrieve the maximum pipe size from /proc and increase LogPipe's pipe
size to that.

set it in one location only, default ON if
* ENABLE_PYTHON
* Distribution == "debian"
* Distribution version >= 12
otherwise OFF

This allows us to set cache variables in any of the subdirectories and
then use these in BareosGenerateDebianInfo later.
Also move the ENABLE_PROXMOX option next to the rest of the cmake
proxmox things.

${rscripts} -> ${BAREOS_SCRIPTS_DIR}

Instead of failing silently, provide a message that the program was not
found on start and status.

* check if process is alive before backing up data
* wait for process to exit (and check return code) before finishing a
  backup or restore
* close the restore process' stdin so it knows we're done restoring
  data

otherwise the core will create a bogus directory based on the virtual
file name we are restoring.

* add force option to overwrite a VM/container on restore
* support on/off yes/no 1/0 on boolean options
* detect unknown extra options

* add comments with sample output
* reorder to match the expected output order
* move default guest names into parser

This makes the plugin adhere to ADR-0004.

Add more debug messages as suggested in code review.

As suggested in code-review enrich the ValueErrors on option assignment
with the name of the option and the value passed.

pct restore requires --rootfs option to restore from stdin.
For now the user has to provide this as a plugin option to Bareos.
