Switch from FLAGS to CONF in misc modules
Switch from FLAGS to CONF in misc modules

Use the global CONF variable instead of FLAGS. This is purely a cleanup
since FLAGS is already just another reference to CONF.

We leave the nova.flags imports until a later cleanup commit since
removing them may cause unpredictable problems due to config options not
being registered.
