SRADA-921: Made features arguments required and removed templates

Changes:
  * TracingFeatureArgument.parseFeatureOptions now throws exception if it could
    not find any feature options in given command line.
  * Implemented TracingFeatureArgument.toStringArray() static method that
    converts given TracingArguments object to its ArrayList<String>
    representation.
  * Removed '-t' option.
  * Replaced CliInternals.selectTemplate with selectFeatureList method's stub.
  * Fixed influenced tests.

Note that tracing will be disabled until CliInternals.selectFeatureList is
implemented.
