<node-proxy,port-proxy> Bug 964212 - Fix init script dependencies

https://bugzilla.redhat.com/show_bug.cgi?id=964212

services are started before init scripts are called during startup

BZ963827 - Logs generated by oo-admin-ctl-gears should include timestamps

The code was actually logging in two different places. The NodeLogger
was already logging to /var/log/openshift/node/platform.log, which
includes the timestamps. The /var/log/openshift-gears-async-start.log
existed before the platform.log and was just a redirection of stdout,
which did not include timestamps. The openshift-gears-async-start.log
is removed with this commit.
Modify NodeLogger to use a format consistent with rsyslog

Example, instead of:
D, [2013-05-22T09:02:27.336207 #7200] DEBUG Loaded cartridge (python, 2.6, 0.0.1)

It will look like:
May 22 10:44:30 DEBUG Loaded cartridge (python, 2.6, 0.0.1)
