Applicability of min-osnr-margin and q-margin to other drafts

[manzoro]

While the wdm-if-tca-list is applicable only to this model, it is not clear why the min-osnr-margin and q-margin are not applicable to optical impairments and WDM tunnel models

See also https://github.com/ietf-ccamp-wg/draft-ietf-ccamp-dwdm-if-param-yang/pull/4/files#r1943318785 for some common definitions for wdm-if-central-frequency

It might be worthwhile discussing this issue in one of the next calls on optical impairments or WDM tunnel

Same also apply for
grouping wdm-if-statistics {

While this grouping seems not applicable to the optical impairments topology model, it is not clear why it is not applicable to the WDM tunnel model
