Fix project name in the table for Cisco N1K profiles

This is a fix to ensure that the project names for the
projects that use the Cisco N1K profiles are correctly
displayed in the tables for the Cisco profiles.
This essentially entails changing "tenant"/"project_id"
to "project" in the forms.py and views.py files;
and changing "project_id" to just "id" in the tables.py
file.

Additionally removing the lines of code for class
EditPolicyProfile from the tables.py file.
This class is not in any use anywhere and also
Policy profiles are uneditable right now. The url
it was referring to was also the wrong one. Made sense
to just do away with it.
