layer0-node-type - change to l0-node-type to make it consistent with the rest of the l0 abbreviation

This is raised during the feedback to YANG doctor, and will be revised after consensus.
Following changes would be needed on,
layer0-node-type -> l0-node-type
layer0-grid-type -> l0-grid-type
layer0-bandwidth-type -> l0-bandwidth-type
layer0-label-range-info -> l0-label-range-info

For alignment with dwdm-n and flexi-n, it would be better to introduce the channel spacing also for the cwdm-n:

draft-ietf-ccamp-layer0-types/ietf-layer0-types.yang

Line 75 in 10acf68

Wavelength (nm) = 1471 + N x 20 ";

Proposed changes:

        Wavelength (nm) = 1471 + N x channel-spacing (measured in nm),
      where 1471 nm is the ITU-T 'anchor wavelength'
        for transmission over the C band; and
      where 'channel-spacing' is defined by the cwdm-ch-spc-type.";

I have just few editorial comments aimed at improving the readability of the code

Please update the revision date
