If the ssh connection test fails and the borg repository wasn't initialized the test runs into a "Fatal: Can't connect" although connecting was successful.

borg will by default create its cache directory in ~/.cache/borg. This
means that during backup runs, borg will read and write quite
extensively from/to this directory.
In some situations, it is rather undesirable to have this amount of IO
activity in this location and it would make sense to tell borg to place
its cache elsewhere. This can help for example with placing the cache on
a hard drive where the added IO load will not have as big of an impact
on other running activity for the system.
This change also makes sure that the cache directory environment
variable is cleared out when the configuration option is unset. This
should avoid unpleasant surprises when this environment variable is set
to some unknown value in the context where backupninja is called, which
could lead to borg reading and writing to random places on the system.
This enables the handlers to be used for hosts which use a non-standard
port, such as is offered by some commercial services. Default to port
22, so it's optional and backwards-compatible.
It seems like only the short output of hwinfo --disk is provided to hardware.txt. I'd suggest we also add disk to the flags for the "complete" output.
That's especially useful when you need to indicate the serial number of a dead drive in order for it to be replaced. Once the disk is dead, using hardware.txt can be the only way to retrieve this info.
This fixes cases where the day component of the when parameter resolved
to a non-zero padded integer under 10, such as "when = 1st at 01"
The comparison against the nowday variable failed consistently since
the date command format used always returned a zero-padded two digit
integer.
The solution chosen is to avoid generating nowday with zero-padding and
remove any zero-padding from whenday parameter using a more thorough
sed pattern which now also removes any non-alphanumeric characters from
the string.
Removing the quote and semicolon characters should be sufficient to
prevent breaking out of the shell command, but this may need reviewed
by someone more knowlegeable in shell scripting.
This allows the handler to fully make use of the advanced command-line
options for "borg create", such as the replaced "exclude*" options and
others like "--read-special" and "--numeric-owner".
The effect of "keep*" options is not straightforward to understand, so
replacing it with a simpler "keep" option, which replicates the
functionality of other backupninja handlers. This also simplifies the
helper, as the use is then only asked how many days of backups to keep.
At the same time, we add "prune_options" which allows for the use of the
"keep*" options as well as other useful prune options, like "--prefix".
