Description

With something like:

mesos-slave \
--image_providers='docker' \
--containerizers='mesos' \
--docker_registry='http://my-registry.fqdn" \
..

Docker fetcher tries to fetch registry's catalog via an HTTPS request,
instead of an HTTP request.

Probably because of:

• https://github.com/apache/mesos/blob/af2a404b59e949163b1d85dcb5ec354ecac02e70/src/uri/fetchers/docker.cpp#L879
• https://github.com/apache/mesos/blob/af2a404b59e949163b1d85dcb5ec354ecac02e70/src/uri/fetchers/docker.cpp#L896

 
{{ string scheme = "https";}}
{{ if (uri.has_fragment(){}}
{{    scheme = uri.fragment();}}
{{ }}}

should probably be:

string scheme = uri.scheme();
