Add Collectd as a Monitor Type
A plugin for collectd is added to use collectd on compute as a monitor type. Monitor files are updated accordingly. The inspector now listens on all interfaces instead of only localhost to enable it to communicate with compute node. JIRA: DOCTOR-86 JIRA: DOCTOR-101 Change-Id: Idc834d428152e4687020eff7d8db36a652b1bf86 Signed-off-by: Umar Farooq <umar.farooq@neclab.eu>
