Consider providing pmlogdump sym link

[myllynen]

All tools processing PCP log archives are of form pmlog* except for the tool to dump log contents which is, of course, pmdumplog.

Consider provider providing a sym link pmlogdump -> pmdumplog (and perhaps even corresponding man page alias) so that all log archive related commands can be seen by tab completion pmlog<TAB>.

Obviously not critical, please feel free to close if not seen as a worthwhile idea. Thanks.
