Adds an optional new configuration format under the remote hosts
configuration segment, allowing the specification of a weight in
addition to the host name.
Weights are used to refactor the active "count" of a host in order to
bring it lower by the following logic:
1. If a host's weight is not specified, it is 1.
2. If a host's weight is 1, its "weighted_count" is equal to its
"count".
3. If a host's weight is greater than 1, its "weighted_count" is equal
to the floor division of its real "count" and its "weight".
So for example, if there are 2 hosts with weights 1 and 2, and there is
currently 1 process running against each, the "weighted_count"s would
be:
host1: 1
host2: 1//2 = 0
And thus host2 would be considered the "least loaded" host. Then, if
another process started:
host1: 1
host2: 2//2 = 1
Resulting in the last host on the list (the first to run a process)
getting the next one, and so on.
This logic should make sense, but I cannot extensively test it.
Closes #8 aspect 1 (aspect 2 is out-of-scope)
