RFR [12]: 8214140: Remove TLS v1 and v1.1 from SSLContext required algorithms

[Sean Mullan]

Please review this change to remove TLS v1 and v1.1 from the SE required 
algorithms for SSLContext. These TLS protocols have various weaknesses 
and are no longer recommended and are being phased out, and thus should 
be removed as requirements.
