They do not play nice with gitlab-workhorse (or rather Golang net/http

Add support to connect gitlab-shell to Unicorn via UNIX socket (v2)
Hello up there.
I'm doing SlapOS port of GitLab, and that means several different services could be running on the same machine, including several GitLabs.
So far all internal GitLab subservices could be glued together via UNIX sockets except gitlab-shell -> Unicorn link, which, when done via local TCP, requires firewall/network namespaces to protect services on one machine from each other.
On the other hand access to UNIX domain sockets is managed via regular UNIX permissions on filesystem, and thus is easier to manage. Besides UNIX domain sockets are well known to be faster compared to TCP over loopback - in particular to have ~ 2 times less latency and ~ 2 times more throughput.
From this point of view it makes sense to teach gitlab-shell to talk to Unicorn via UNIX socket and switch to that mode by default eventually.
I've just made a patch for this. Please apply.
Thanks beforehand,
Kirill

It is well known that UNIX sockets are faster than TCP over loopback.
E.g. on my machine according to lmbench[1] they have ~ 2 times
lower latency and ~ 2-3 times more throughput compared to TCP over
loopback:
*Local* Communication latencies in microseconds - smaller is better
---------------------------------------------------------------------
Host OS 2p/0K Pipe AF UDP RPC/ TCP RPC/ TCP
ctxsw UNIX UDP TCP conn
--------- ------------- ----- ----- ---- ----- ----- ----- ----- ----
teco Linux 4.2.0-1 13.8 29.2 26.8 45.0 47.9 48.5 55.5 45.
*Local* Communication bandwidths in MB/s - bigger is better
-----------------------------------------------------------------------------
Host OS Pipe AF TCP File Mmap Bcopy Bcopy Mem Mem
UNIX reread reread (libc) (hand) read write
--------- ------------- ---- ---- ---- ------ ------ ------ ------ ---- -----
teco Linux 4.2.0-1 1084 4353 1493 2329.1 3720.7 1613.8 1109.2 3402 1404.
The same ratio usually holds for servers.
Also UNIX sockets, since they reside on filesystem, besides being faster with
less latency, have one another nice property: access permissions to them are
managed the same way access to files is.
Because of lower latencies and higher throughput - for performance reasons, and
for easier security, it makes sense to interconnect services on one machine via
UNIX sockets and talk via TCP only to outside world.
All internal services inside GitLab can talk to each other via UNIX socket
already and only gitlab-shell was missing support to talk to Unicorn via UNIX
socket.
Let's teach gitlab-shell to talk via UNIX sockets.

~~~~
In this patch we
- add URI::HTTPUNIX to handle http+unix:// URI scheme
- add Net::HTTPUNIX to handle "connect via unix socket and then talk http"
- adjust GitlabNet#http_client_for() accordingly
- adjust documentation in config.yml.example
The http+unix:// scheme is not reinvented anew: the idea about its structure is
quite logical an was already established at least in requests-unixsocket python

If a repository contained a broken symlink named 'hooks', this would
raise ENOENT in lib/gitlab_projects.rb, which got ignored in
bin/create-hooks. This commit fixes that by making sure we handle
broken symlinks in lib/gitlab_projects.rb.

'gcryptsetup' is a special git-annex feature that does its own

Remove keys from authorized_keys in-place
This will speed up the rm-key operation. The downside is that
authorized_keys will not shrink when you remove a key. If this ever
becomes a problem it can be fixed by running 'rake gitlab:shell:setup'.

This intention of this change is to make the normal flow of execution
easier to read, and to prevent mistakes in deeply nested if-else trees.
