Add a check that monitors crash dumps. The specified crash directory is scanned for sub-directories named 'YYYYmmddHHMM' which contain the dump files. The 'dump_count' metric is the number of sub-directories (i.e., the number of crash dumps present) and the 'value_meta' dict contains the date-/timestamp of the most recent crash.
