ssh support for 3rd party components

[dbones]

some components are set up within a firewalled environment

https://github.com/dbones-labs/lab-dev/blob/main/src/Dev/v1/Components/Postgres/Postgres.cs#L17

public class PostgresSpec
{
    [Required] public string Credentials { get; set; } = string.Empty;

    public bool UseSshTunnel { get; set; } = false;
}

by setting the UseSshTunnel then the Credentials needs to store extra information to allow setting up an SSH tunnel
