Make Python opm package a namespace package

Browse Source 
Convert the Python opm package from a regular package to a namespace
package such that opm-simulators and opm-common can contribute to the
package from different filesystem paths. In this way, the two packages
opm.simulators and opm.io (in opm-common) can have a different parent
filesystem path.
