Symbolic local pref values should be concrete after solve

[alehed]

The local pref values are the only things that are symbolic in the config, therefor they should be used to set the path preference and not be symbolic after running NetComplete.

• Test-case: test_symbolic_local_pref in tests/test_bgpver.py.

This is similar to Issue #12

[alehed]

Also here the solver claims unsat. I might look into it tomorrow.

The problem is more specifically seen in #19. Closing until the problem lies with the local pref.

[alehed]

Ok, a specific problem popped up again. Setting the SetLocalPref action to symbolic causes the test to fail for no good reason.

[ahassany]

Is this still an issue, I don't see the test case anymore in the code

[alehed]

I think this particular thing is not an issue any more.
