I think it is OK to not have a unit-test for this patch since this only changes configuration
parameters. I have tested this manually and verified that it works

> RAID parity files are merged into HAR archives periodically. This is required to reduce
the number of files that the NameNode has to track. The number of files present in a HAR archive
depends on the size of HAR part files - higher the size, lower the number of files.
> The size of HAR part files is configurable through the setting har.partfile.size, but
that is a global setting. This task introduces a new setting specific to raid.har.partfile.size,
that is used in-turn to set har.partfile.size
