[consensus] 'runtime' tag for consensus log FI flags
[consensus] 'runtime' tag for consensus log FI flags

Added the 'runtime' tag for the following consensus log fault-injection
flags:
  * log_inject_latency
  * log_inject_latency_ms_mean
  * log_inject_latency_ms_stddev
  * log_inject_thread_lifecycle_latency_ms
  * fault_crash_before_append_commit

That's just to reflect their current nature "de facto".
