Changes include:

- Closing the used global FD using `ceph_close_my_fd()`
during delegreturn.
(Otherwise subsequent WRITE & READ would hang after a
delegreturn.)

- Enabling Read and Write file delegations by switching delegation
option from `FSAL_OPTION_FILE_READ_DELEG` to
`FSAL_OPTION_FILE_DELEGATIONS`.

- In `nfs4_op_open`, store the associated open state key
(`stateid_other`) within the delegation state to open the
files using this information later via fsal_start_io.

- Code changes to allow delegation option parsing from
EXPORT_DEFAULT, EXPORT, CLIENT blocks

- Added FSAL_O_ANY flag for write delegation and delegreturn cases.

- Removed exit label in ceph_fsal_lease_op2 to avoid returning
success whenever fsal_start_io returns failure.
