ssh-rsa key is no longer allowed in CentOS 9

[Takashi Kajinami]

The octavia::worker class generates the ssh key for amphora instances when the manage_keygen parameter is set to True.

However currently the ssh key is always generated with rsa type which is no longer allowed in CentOS 9.

    Support customizing ssh key type

    This change introduces a few new parameters to customize type of
    the ssh key automatically generated. This is required especially in
    recent operating systems like CentOS 9 which no longer allow RSA key
    by default.
