Support Python 3.12 by not using ssl.wrap_socket

[SunilMohanAdapa]

• ssl.wrap_socket() has been deprecated since Python 3.7[1]. In Python 3.12, the function has been removed and causes hard failure.

• Recommended way to replace ssl.wrap_socket() is to use SSLContext.wrap_socket(). To get the exact earlier behavior:

  • CA certificates are loading using SSLContext.load_verify_locations().

  • Certificate for our peer is loaded using SSLContext.load_cert_chain().

  • Ciphers are set using SSLContext.set_ciphers().

  • cert_reqs is replaced with context.verify_mode.

  • SSLContext.check_hostname has not been set to true because there is a custom implementation checking hostnames.
