Various options are available when formatting the different file systems
we support. This change implements a hash to capture many of the
different options we use throughout a test deployment.
* BTRFS: set metadata for test volumes to single.
the metadata on our loopback devices was defaulting the the file-system
default of DUP (duplicate) which is reasonable on a production
deployment however on a loopback device it makes more sense to set the
data and metadata options to "single". This will help eliminate the
issues were seeing with intermittently full file-systems.
* XFS: set block sizes, placement groups, and do not issue discards at
create.
This will speed up the time it takes to format an XFS partition as
well as ensure things remain speedy under load.
* EXT4: speed up directory lookups
Use hashed b-trees to speed up name lookups in large directories.
