Introduce new parameter names to align with the spec?

[MaisenbacherD]

When adopting the libnvme API changes we have the possibility to fix the naming of parameter options for spec consistency.
E.g.:

nvme-cli/nvme.c

Line 6504 in 37f0290

OPT_BYTE("ms", 'm', &cfg.ms, ms),

Where ms is defined as mset in the spec.
For backwards compatibility we should maybe keep the old name and introduce the "correct" name as a new option that maps to the same variable.

This can be discussed in the community.
