[tserver] unify logging on rejected write requests
This patch contain a minor clean up on the logging of rejected write
requests and other minor improvements, making the logs more useful
for post-mortem analysis and troubleshooting in some scenarios:
* unified the prefix for log messages on rejected write requests,
so it's now easier to search in the logs
* log about all rejected write requests using time-based throttling
wrapper KLOG_EVERY_N_SECS(.., 1)
* log about all rejected write requests using INFO severity unless
going over the --memory_limit_warn_threshold_percentage threshold
for memory pressure rejections; use WARNING severity for the latter
* changed TabletServerErrorPB from UNKNOWN_ERROR to THROTTLED when
rejecting a write request due to a throttling condition
* use static instances of Status objects to avoid allocating and
freeing memory for status messages upon rejections
