Paul Gier f79b55d057 cmd/prometheus: remove govalidator for url validation ... The usage of govalidator is redundant with the call to url.Parse for url validation. Removing it has the following benefits: - The explicit error message is displayed instead of just a generic valid/invalid message - Slightly smaller code with one fewer external dependency - Speed improvement by removing duplicate call to url.Parse (inside govalidator.IsURL() - Resolves issue #2717 The only potential drawback of removing govalidator is that certain URLs will be considered valid which were previously invalid. For example: - URLs with hostnames that start and/or end with an underscore (http://_example.com_) - URLs with hostnames that contain some special characters (http://foo&*bar.org) These are valid URIs according to RFC 3986 and valid domain names per RFC 2181, however they are not valid hostnames per RFC 952.		2017-10-04 10:08:34 -05:00
