dynamic downstream job creation based on targets

Instead of having a hard coded list of available targets, this approach
makes use os the dumpinfo.pl script that automatically finds available
targets existing in the OpenWrt buildroot. The advantage is to
automatically adapt to available targets in different branches.

Additionally the tagging of SDK containers is improved. While it is
still possible to use SDK based on target tag, it is now also possible
to chose the target based on architecutre. This way less SDK container
are build as one architecutre covers multiple targets.
