Log SSH errors when running "repmgr cluster (matrix|crosscheck)"

Browse Source 
Previously repmgr would abort with an unhelpful message about being
unable to parse CSV output.

With this commit, it will continue running, and display a list of
inaccessible nodes as an addendum to the main output (unless --csv
or --terse options are specified).

Addresses GitHub #246.
