Issue #21013 : Enhance ssl.create_default_context() for server side contexts
...
Closes #21013 by modfying ssl.create_default_context() to:
* Move the restricted ciphers to only apply when using
ssl.Purpose.CLIENT_AUTH. The major difference between restricted and not
is the lack of RC4 in the restricted. However there are servers that exist
that only expose RC4 still.
* Switches the default protocol to ssl.PROTOCOL_SSLv23 so that the context
will select TLS1.1 or TLS1.2 if it is available.
* Add ssl.OP_NO_SSLv3 by default to continue to block SSL3.0 sockets
* Add ssl.OP_SINGLE_DH_USE and ssl.OP_SINGLE_ECDG_USE to improve the security
of the perfect forward secrecy
* Add ssl.OP_CIPHER_SERVER_PREFERENCE so that when used for a server side
socket the context will prioritize our ciphers which have been carefully
selected to maximize security and performance.
* Documents the failure conditions when a SSL3.0 connection is required so
that end users can more easily determine if they need to unset
ssl.OP_NO_SSLv3.

Issue #20995 : Enhance default ciphers used by the ssl module
...
Closes #20995 by Enabling better security by prioritizing ciphers
such that:
* Prefer cipher suites that offer perfect forward secrecy (DHE/ECDHE)
* Prefer ECDHE over DHE for better performance
* Prefer any AES-GCM over any AES-CBC for better performance and security
* Then Use HIGH cipher suites as a fallback
* Then Use 3DES as fallback which is secure but slow
* Finally use RC4 as a fallback which is problematic but needed for
compatibility some times.
* Disable NULL authentication, NULL encryption, and MD5 MACs for security
