Log: controller: add resource agent meta-data flag functions
... instead of set_bit()/clear_bit(), which improves trace messages like:
Bit 0x00000001 set by some_function:100
to:
Resource agent flags 0x00000001 (ra_supports_reload) for some:resource:agent set by some_function:100
or:
Resource agent parameter flags 0x00000001 (ra_param_unique) for some_param set by some_function:100
