Remove non-needed org.eclipse.tycho's osgi (but a lot left)

Remove non-needed org.eclipse.tycho's osgi (but a lot left)

see https://git.opendaylight.org/gerrit/#/c/51520/
and https://git.opendaylight.org/gerrit/#/q/topic:tycho

I'll like to block use of dependency tycho in odlparent ASAP.

This project has quite a lot of uses of org.eclipse.tycho
related to console commands... could we ask you if you would
mind to change that to use the Karaf Console API instead?

your poject (SNMP4SDN) is the only one in ODL still using
this API (and in openflowplugin there is 1 use like this).
