[REQ] Support git repositories other than github.com

[qmuntal]

I'm hosting an auto generated go client in an private instance of github enterprise and the generated mod.go file points to github.com instead of my own host.

I would like to be able to configure the host of my git repository using a cli parameter, for example --git-host, in the same way as it is done for --git-user-id and --git-repo-id.

Without this parameter, the only alternatives I have are:

• Manually update the auto generated code, which creates a maintenance problem when regenerating the code.
• Create an custom extension with the hard-coded host, which seem to be an overkill to just modify an url

That sounds reasonable. Would you have time to contribute the enhancement?

[qmuntal]

Yes I do.
@wing328 do you know if this parameter could be used in more places other than git_push.sh and go.mod? My initial focus will be this two files.

[wing328]

We can start with these 2 files first.

Later we can roll it out to other files like PHP composer config file, Ruby client's README, etc
