[SSH connection] Support for proxy connections

Is your feature request related to a problem? Please describe. I am currently trying to use ssh-profile to access a SAS server that is only available after a proxy jump. When trying to connect I get the error:

getaddrinfo ENOTFOUND <server-name-redacted>

Describe the solution you'd like I would like the ssh-profile to work with proxy jumps

Describe alternatives you've considered NA

Additional context I am on MacOS I currently have the proxyjump setup as follows in my ~/.ssh/config file

Host <proxy-server>
    AddKeysToAgent yes
    UseKeychain yes
    IdentityFile ~/.ssh/id_rsa

Host <host-server>
    AddKeysToAgent yes
    UseKeychain yes
    IdentityFile ~/.ssh/id_rsa
    ProxyJump <proxy-server>

(ssh'ing from the terminal with this setup works as expected)

I have my SAS profile setup as follows:

            "server-sas": {
                "connectionType": "ssh",
                "host": "<host-server>",
                "saspath": "/opt/sas/SASHome/SASFoundation/9.4/sas",
                "username": "gowerc",
                "port": 22
            }

I think this request was originally raised here though looks like it may have gotten overlooked as I forgot to create this ticket to separate it from the original issue posted in that issue.

Environment SAS version = 9.4 RHEL = 8.8
