Use specific versions for odlparent imports

Use specific versions for odlparent imports

Felix (or something related) doesn't look for snapshots in version
ranges, which breaks integration/distribution, so we can't use version
ranges for feature dependencies (even though they don't currently end
up in the generated features) until we switch to release artifacts.

See
https://jenkins.opendaylight.org/releng/job/netconf-distribution-check-carbon/1468/
for an example of a broken build.
