def _sanitize_sar_str_param(self, param):
if param is None:<EOL><INDENT>return None<EOL><DEDENT>return str(param)<EOL>
Sanitize SAR API parameter expected to be a string.

If customer passes something like 1.0 as SemanticVersion, python
converts it to a float instead of a basestring, so need to explicitly
convert it for API calls to SAR that expect a string input.
