hostinfo_mergehost

Take the details of the two hosts and combine them into one:

% host_merge [opts] --src srchost --dst dsthost
    -k        Just kidding, don't do anything
    -v        Be verbose about what is happening
    -f        Force collisions to be resolved in the dst hosts favour

• All srchost data will be copied to the dsthost, unless the dsthost already has that key set
• The srchost will be deleted after the data has been copied across
• This is used for when two hosts have been accidentally created with different names and then someone realises that they are actually the same host.
