Proposal: Add Docker Who #9042 

My first take with go. Please be gentle ;)
Wondering; perhaps it's possible to use the People hash map to the actual name generation as well. Having the names in two separate places brings a chance that they get out of sync.

Of course, that would require changes in the names-generator and (being a Go noob) don't know if getting a random value from a hash map is less performant than an array.
