Define a composite service that propose high-level services : served by gitlab api or JGit according to the case
We set the git property sslVerify to false to bypass ssl checks of the gitlab server.
Here how the gitlabToken and gitlab.server.url fields are valued (spring boot way):
gitlab.server.url=https://gitlab.foo.com/foo-ns/foo-project.git
gitlab.token=tokenFooBar

Define a generic service that performs gitlab api requests with ssl checks disabled
Here how the gitlabToken and gitlabApiBaseUrl fields are valued (spring boot way):
gitlab.api.base-url=https://gitlab.foo.com/api/v4/projects/4581
gitlab.token=tokenFooBar
Here 4581 is the project id in gitlab.
