rgw: object lock uses 64-bit encoding for RetainUntilDate

the default encoding of ceph::real_time truncates seconds to uint32_t,

encoding: add round_trip_encode()/decode() for chrono types

the default encodings for chrono types were made to be
backward-compatible with utime_t, so truncated seconds to 32 bits

adds new functions that encode these chrono types using their underlying
representation, which for ceph::real_time and ceph::timespan is
'nanoseconds as uint64_t'

mgr/snap_schedule: validate fs before execution

Stop command execution if there are more than one filesystem and --fs
argument is missing in command-line, i.e. do not use the first fs in the
fsmap if there are more than one filesystem.
This is to ensure that user doesn't mistakenly run the command against
the first fs by missing to specify the desired fs.

mds: change priority of mds rss perf counter to useful

The PR changes the priority of the mds_rss metric from Debug to useful

doc/radosgw: edit "Add/Remove a Key"

Edit the section "Add/Remove a Key" in doc/radosgw/admin.rst. Each
operation (e.g. "Adding an S3 key pair for a user", "Removing an S3 key
pair for a user") now has its own subsection. This increased granularity
should make it easier in the future to link to each of these specific
operations, if needed.
