[Bloat] gitlab network optimizations

[Dave Taht]

Most cloud operations websites are kept internal. gitlab's is not,
which is pretty cool. In looking over this:

https://gitlab.com/gitlab-com/gl-infra/production/-/issues/6768

They are tracking tcp syn retransmits, but not drops or other
congestion control related info. And
also

sysctl net.ipv4.tcp_notsent_lowat=4294967295;

where we've been getting good results with that set as low as 32k.
Anyone know anyone at gitlab?
