commands: pass through GIT_PROTOCOL envvar provided by clients

Closes #273

See merge request gitlab-org/gitlab-shell!364

Both git-upload-pack and git-receive-pack services inspect the
GIT_PROTOCOL environment transferred via SSH in order to decide which
protocols are supported by a given client. Currently, we don't use the
environment variable at all, though, but instead forward the GitProtocol
field of the access verification response.

Improve this by passing on the GIT_PROTOCOL environment variable
provided by the client as-is.

Use Go 1.12 - 1.14

Add support for Gitaly feature flags

See merge request gitlab-org/gitlab-shell!351

gitaly#1846

Gitaly does not store or remember feature flags. We must pass them in as
metadata on each request. This MR adds plumbing to pass Gitaly feature flags
supplied by gitlab-rails to the Gitaly server as gRPC request metadata.
