Select best matching target environment for p2install

Currently a p2 provisioned install always use the running target to
provision what is also the best option most of the time. In case where
there is no matching one this can lead to failing installs.

This now allows to specify the environments and shows a warning if the
running one does not has any match.

(cherry picked from commit 3f41779)
