glusterd/volgen: refactor some things

- use macros for exported volume tunables
- introduce glusterd_volinfo_get_boolean as retrieval of boolean
  optuions was a recurring pattern and became somewhat cumbersome

Also fixed illegal access to volinfo dict.
@pranith: use always the glusterd_volinfo_get* API for that purpose
so that defaults are taken to consideration.
