ref(client): use logging module

With this change, we can now have more power over how we filter and
deal with our logs.
feat(client): add colorized logging
fix(logger): properly parse incoming syslog messages
fix(logger): remove priority from log messages

Our current log message follows this format:

    2014-09-02 09:40:00 deis[api]: message

Where `deis[api]` is the tag. Removing the priority keeps the
log message the same format as before.

According to https://coreos.com/docs/cluster-management/setup/cloudinit-cloud-config/ it should be "public-ip" not "public_ip"
