Support for SSH alias

[tashi21]

Can support also be added for ssh aliases? Because I have different identity files for my different git accounts, and my company repo is private, I need to setup my Git config and SSH config accordingly. Now that there is support for custom base URLs, can we also add support for an alias of a URL?

My Git config:

; clone all raaho repos via ssh only using correct identity file
[url "ssh://git@useraaho.com/raaho"]
  insteadOf = https://github.com/raaho

[url "ssh://git@useraaho.com/raaho"]
  insteadOf = git@github.com:raaho

My SSH config

Host useraaho.com
  AddKeysToAgent yes
  HostName github.com
  IdentityFile ~/.ssh/id_ed25519_raaho_github
  IdentitiesOnly yes
  PreferredAuthentications publickey
  UseKeychain yes
  User git

settings.json could look something like this:

"git_hosting_providers": [
    {
      "alias_of": "https://github.com",
      "base_url": "https://useraaho.com",
      "name": "Raaho",
      "provider": "github"
    }
]

If alias_of is present, base_url needs to be replaced by it when generating the permalink.
