use variables instead facts mostly everywhere

set_fact is stupid; they persist through multiple role executions; for
example, you cannot do this:

    set_fact:
      foo: '{{ foo | default("bar") }}'

If somebody calls the role and defines foo, it will always be set to
that value forever, even for subsequent role calls.
