Bucket change during integration (#835)

* set up fhour with multiple values

* updates for diag time

* add fixes for two bucket

* Update fhzero global attribute at runtime

* Update to speed uo writing restart files

* allow fhzero to be non-integer

* Move ESMF_InfoBroadcast call outside ESMF_VMEpochEnter/ESMF_VMEpochExit section to avoid hanging
