This commit updates the matchers parser to reject unquoted openmetrics escape sequences. As an example, foo=bar\n will no longer parse, and must instead be written as foo="bar\n". This avoids an issue where the input is valid in both the matchers and classic parsers, but results in two different parsings. Signed-off-by: George Robinson <george.robinson@grafana.com>
