    A high-level representation of a session with an SSH server.  This class
    wraps `.Transport`, `.Channel`, and `.SFTPClient` to take care of most
    aspects of authenticating and opening channels.  A typical use case is::

        client = SSHClient()
        client.load_system_host_keys()
        client.connect('ssh.example.com')
        stdin, stdout, stderr = client.exec_command('ls -l')

    You may pass in explicit overrides for authentication and server host key
    checking.  The default mechanism is to try to use local key files or an
    SSH agent (if one is running).

    Instances of this class may be used as context managers.

        Connect to an SSH server and authenticate to it.  The server's host key
        is checked against the system host keys (see `load_system_host_keys`)
        and any local host keys (`load_host_keys`).  If the server's hostname
        is not found in either set of host keys, the missing host key policy
        is used (see `set_missing_host_key_policy`).  The default policy is
        to reject the key and raise an `.SSHException`.

        Authentication is attempted in the following order of priority:

            - The ``pkey`` or ``key_filename`` passed in (if any)
            - Any key we can find through an SSH agent
            - Any "id_rsa", "id_dsa" or "id_ecdsa" key discoverable in
              ``~/.ssh/``
            - Plain username/password auth, if a password was given

        If a private key requires a password to unlock it, and a password is
        passed in, that password will be used to attempt to unlock the key.
