Description

Right now, "hdds.scm.replication.command.deadline.factor" is a fraction. For long durations such as 60 minutes, the difference between SCM deadline and Datanode deadline will be 60 - 60 * 0.9, which is 6 minutes. This is a significant difference, so perhaps this configuration should be a duration instead, like 30 seconds.

Currently the APIs provided by RM expose the DN deadline as a parameter. We could remove this and just let the RM decide a deadline for commands in the DN.
