No ability to use custom salt jinja2 filter in custom cloud deploy scripts

[rf-vivanovs]

Description of Issue/Question

When writing deploy scripts vm, opt, and minion dicts are available.
minion is str, but vm and opt are dicts, and we can't dump them directly.

The problem is that if you need to dump/pass information that is json/yaml, you don't have the ability to do that from the deployer script, because no json/yaml filter is available.

I'm not sure if it is intended or not, but would be nice to have an ability to use them.

Setup

I have a custom cloud deployer with "custom" opts:

minion:
  master: xxx
  grains: {}
env-specific-settings:
  some_yaml:
    more_yaml:
      - more_yaml

Then in my custom deployer script I have (just an example)

cat > /tmp/dump <<EOF
{{ opts }}
{{ opts.my_value }}
{{ opts | yaml(False) }}
EOF

Steps to Reproduce Issue

If you deploy a VM with the custom deployer script you will see an error and traceback:

                    File "/usr/lib/python2.7/site-packages/jinja2/environment.py", line 742, in handle_exception
                      reraise(exc_type, exc_value, tb)
                    File "<unknown>", line 14, in template
                  TemplateAssertionError: no filter named 'yaml

Runner function 'cloud.profile' failed.

and the raw dump of data looks like:

{u'key_cache': u'', u'regen_thin': False, u'tcp_master_workers': 4515, u'external_auth': {}, u'fileserver_backend': [u'gitfs', u'roots']....
