Value Regex does not function with numeric values (perhaps graphite only?)

[elvenavatar]

The regex values were not being applied to numbers. (Grafana 4.4.3 - Graphite Datasource) - I was unable to find a suitable way of getting graphite to round its values (perhaps there is one that I'm unaware of). But In any case, I feel the behavior of the valuedisplayregex is improved by having it also support numerical values.

I modified dist/status_ctrl.js as follows to achieve the desired result: (I don't typically code in javascript - I didn't submit it as a patch as I suspect you may wish to alter significantly)

It uses the original filter for number in the cases where regex fails.

                                            coreModule.filter('numberOrTextWithRegex', function () {
                                                    var numberOrTextFilter = function numberOrTextFilter(input, textRegex) {
                                                    var stringInput;
                                                    var failReturn;

                                                    if (angular.isNumber(input)) {
                                                       stringInput = input.toString();
                                                       failReturn = _this2.filter('number')(input);
                                                    } else {
                                                       stringInput = input;
                                                       failReturn = input;
                                                    }

                                                    if (textRegex == null || textRegex.length == 0) {
                                                        return failReturn;
                                                    } else {
                                                        var regex = void 0;

                                                        try {
                                                            regex = new RegExp(textRegex);
                                                        } catch (e) {
                                                            return failReturn;
                                                        }

                                                        var matchResults = stringInput.match(regex);
                                                        if (matchResults == null) {
                                                            return failReturn;
                                                        } else {
                                                            return matchResults[0];
                                                        }

                                                    }
                                                    };
