[networking-midonet]: transition pike, queens and rocky to eol

This patch transitions stble/pike, stable/queens stable/rocky branches
to End of Life. This was discussed on Neutron CI meeting (see [1]) and
a mail was sent out to the community (see [2]).
These branches cannot be used anymore and will be deleted if this patch
merges.
