Add a gitlab:tcp_check rake task
What does this MR do?
Adds a rake task that checks whether TCP connectivity to a given host + port is working.
It can be used like:
rake gitlab:tcp_check[example.com,5432]
Are there points in the code the reviewer needs to double check?
I don't see any need for this to be EE-specific so I put it in gitlab-ce. It could have gone in omnibus instead, but I didn't see a strong need for that and it's usable by more people here.
Why was this MR needed?
Geo documentation needs to include a step where we check TCP connectivity to a remote host.
Screenshots (if relevant)
# Missing arguments
$ rake gitlab:tcp_check
Please specify a host and port: `rake gitlab:tcp_check[example.com,80]`
# Successful connection over IPv6
$ rake gitlab:tcp_check[google.com,443]
TCP connection from [2001:ba8:1f1:901:228:f8ff:fe7a:4f2c]:58256 to [2a00:1450:4009:815::200e]:443 succeeded
# Successful connection over IPv4
$ rake gitlab:tcp_check[10.0.1.1,443]

# Failed connection due to firewall -j REJECT
$ rake gitlab:tcp_check[google.com,5432]
TCP connection to google.com:5432 failed: Connection refused - connect(2) for 216.58.206.78:5432
Check that host and port are correct, and that the traffic is permitted through any firewalls.
