poor rpmconf plugin documentation

[fhanzlik]

In rpmconf plugin documentation IMO should be better described things as .rpmnew/.rpmsave or original config file deletion and how merge function works.
Also, doc says: "For list of valid frontends see rpmconf(8)." - but on rpmconf man page is no list of them.

-f<type>, --frontend=<type>
      Define which frontend should be used for merging. Valid  options
      are:  vimdiff,  gvimdiff,  diffuse, kdiff3, meld, sdiff and env.
      When set to env, the command to use is taken from  the  environ‐
      ment variable $MERGE. The default is env.
