This commit forces the use of LUKS1 in cryptsetup.
Centos uses LUKS2 by default in cryptsetup, ubuntu uses LUKS1.
Formating a LUKS2 block device is way longer than formating a LUKS1
device (15 sec vs 8 sec in my env) and LUKS2 doesn't provide any
significant features for octavia (it only improves recovery and
metadata).
The commit aslo limits the creation of more than 1 block ram device
(amphora doesn't need 16 ram devices), which reduces startup time.

A recent patch[1] added --pbkdf-memory to the cryptsetup command line
to limit the memory cryptsetup is using. However, some distros use
an older version of cryptsetup that does not need this setting.
This patch adds logic to detect this and run the commands without
--pbkdf-memory.
