start converting dnssec system test to python/jinja2

Browse Source 
- changed named.conf.in to named.conf.j2 in all server directories that
  don't currently need to use copy_setports() during the test.
- converted the tests that use ns5 to python, and replaced
  named1.conf.in and named2.conf.in with a jinja2 template instead.
  the only remaining server that still needs copy_setports() is ns4.
- removed ns4/named5.conf.in, and moved its functions to ns5 (which
  is supposed to be for servers with broken trust-anchor configurations,
  so it should have been there in the first place). converted the tests
  that used that ns4 configuration to use ns5 with jinja instead.
- revised the remaining ns4 configurations (named[1-4].conf.in) to
  minimize the differences between them. this will make it easier to
  convert it into a jinja2 template later.
