Add Guru Meditation Report Functionality to Neutron

Registered by Zang MingJie on 2014-11-26

GMR can aid in debugging neutron by providing lots of detail about a running
process, including configuration, native thread stack trace and greenlet stack
traces.

GMR is intended to be triggered by sending USR2 signal to a neutron process, If
the process is a daemon, the report will be placed inside logdir. Otherwise,
the report will output to the console.
