Hammer CLI

Arrays in key-value parameters currently can't contain spaces which is a bit unintuitive. Parsing of the following:

hammer host create --parameters packages='[vim, tmux]'

results in:

{"packages"=>["vim", " tmux"]}

Note the additional leading space in tmux.

Also

hammer host create --parameters formula='a=b+1'

gets parsed wrongly as:

{"formula=a"=>"b+1"}

but it's a minor issue.
