Make ruby SDK handle schemed collector url
Currently, when setting up analytics, the GitLab UI gives the collector url including the https://
schema. This will fail requests when used with GitlabSDK::Client
[as Snowplow SDK expects schema-less urls]. We should make it so that GItlabSDK works also when initialized with a url that has a schema, to make the usage of it easier.
