BMC: Store RedundancyPriority on System.

This commit extends the functionality of the BMC software updater by
preserving RedundancyPriority values through any kind of reset.

This is accomplished by storing priority values in serial files in
/var/lib/obmc/phosphor-bmc-code-mgmt/ using the Cereal library. Each
time a priority value is modified, the value in the corresponding
version file is adjusted.

Resolves openbmc/openbmc#2125
