Switch osgeo7 ssh to 2222 so 22 can be reserved for hosts

[robe]

I'm planning to change osgeo7 host ssh port to 2222

that way if we really need it, we can use 22 for containers.

When I do I'll change the documentation accordingly.

Done and I updated both the wiki or ​https://gitea.osgeo.org/sac/osgeo7 with these details

so now the only way to get into the host server is using the 2222 port and via our admin account

ssh tech_dev@osgeo7.osuosl.org -p 2222 

Note only those whose keys are installed have access to the host namely wildintellect, strk, robe,martin

There is also access via the KVM, but that requires you have OpenVPN connected to OSUOSL network (which robe and wildintellect have -- and in theory strk and martin may have if they ever set themselves up)
