Support templating of var names in a similar manner as labels. Add
support for a new 'varsTemplate' field to the feature rule spec which is
treated similarly to the 'labelsTemplate' field. The value of the field
is processed through the golang "text/template" template engine and the
expanded value must contain variables in <key>=<value> format, separated
by newlines i.e.:
- name: <rule-name>
varsTemplate: |
<label-1>=<value-1>
<label-2>=<value-2>
...
Similar rules as for 'labelsTemplate' apply, i.e.
1. In case of matchAny is specified, the template is executed separately
against each individual matchFeatures matcher.
2. 'vars' field has priority over 'varsTemplate'
