Remove opm-common dependency

Severs the code dependency on opm-commmon. There was no actual
functional dependency here, with the exception of some enable/disable
warning headers. To properly make opm-parser a stand-alone module the
usage of these headers have been removed and the dependency on
opm-common is gone.
