There's a lot of demand for the Gitlab badges (#541) and the PR has been lingering, so I thought I'd start off one of the simple ones as a new-style service. This one is SVG-based, so it shouldn't require the API-token logic which could use some more testing and will require us to create an app and configure it on our server.
We don't have any validation in place for `queryParams`. Probably this should be added to BaseService, though for the time being I extracted a helper function.
Thanks to @LVMBDV for getting this work started in #1838!
* upgrade to Joi 14
Joi 14 throws an exception on regexes which use the `g` flag
see https://github.com/hapijs/joi/issues/1615
semver-regex uses the `g` flag
https://github.com/sindresorhus/semver-regex/blob/master/index.js
so in order to upgrade Joi, I've swapped out semver-regex
We'll use joi-extension-semver for semver validation now
* use isVPlusDottedVersionNClauses in jetbrains tests
some of these projects use version numbers like
v1.7 or
v3.0.0.141
