Eunsoo Park 32cd153791 Make Neutron LBaaS Activation Timeout configurable 
This changes _ACTIVATION_TIMEOUT of LBaaS driver from constant to
configurable value in order to make it flexible to production
environment.

This commit also increases the timeout value in DevStack plugin to make
sure Octavia has time to run Amphorae in the gate.
