systemd-analyze: filter dot output
Make "systemd-analyze dot" output only lines with units matching given glob(7) patterns. Add --from-pattern and --to-pattern options. Without any patterns all relationships are printed as before. A relationship must match the follwing expression: (isempty(from) || from[0] || from[1] || .. || from[n]) && (isempty(to) || to[0] || to[1] || .. || to[n]) && (isempty(P) || P[0] || P[1] || ... || P[n]) where from[] and to[] are lists of patterns provided with subsequent --from-pattern and --to-pattern respectively. P[] is a list of additional patterns provided after the "dot" subcommand.
