[Feature Request] - ssh ProxyCommand/ProxyJump

[jameschenjav]

I have several hosts configured in my ~/.ssh/config, that protected with company's VPN or AWS session manager. There are some examples:

Host foo.i-123456
  User xxx
  ProxyCommand aws ssm start-session --profile foo --target i-123456 --document-name AWS-StartSSHSession --parameters 'portNumber=22'
  IdentityFile ...

Host vpn-gateway
  HostName xxx
  User xxx
  Port xxx
  IdentityFile ...

Host bar
  HostName bar.com
  User bar
  ProxyJump vpn-gateway
  IdentityFile ...

How can I connect to them? I have tried termscp scp://bar termscp sftp://bar and did not work.
