[NFS-Ganesha-Support] Branch next AND V6-stable

Tag:V6.5 Note: V6-stable branch is also created with this push. Merge Highlights This merge does provide some small "features" with new config options, however, the defaults result in no change in behavior. Again, these patches are accepted to work with Google to closer match their internal repos. There is a new option to enable/disable sticky grace that defaults to disable, returning Ganesha to earlier grace period behavior. Without the support from the recovery backend, sticky grace could cause problems warranting disabling it by default. Some new Prometheus metrics are added. * SAL/sal_metrics.c: Added SAL static metrics. * nfs4_op_readdir: Always return NFS4ERR_TOOSMALL if we didn't have enough space for a single entry * FSAL/FSAL_CEPH/handle.c: Moved tracepoint to reduce indentation * Resolve compilation warnings * common_utils: Added additional documentation to doc strings * do not crash when ref count is greater than 1 * Implement log rotation/compress for Ganesha * Fix the issue where the nfs4_op_write function always returns 0. * Sticky Grace Configurable option: * nfs_metrics.c: Fix code style issues * nfs_main.c: Use dup2 to simplify function calls * add root_kerberos_principal param * add read_access_check_policy param Signed-off-by: Frank S.
