Adding more options to the SSL configuration (#2039)

[LannyRipple]

• Provides ClientSSLConfig FromJavaxNetSsl to allow configuring client SSLContext using a javax.net.ssl.KeyManagerFactory and/or a javax.net.ssl.TrustManagerFactory.
• Only partially addresses #2039.

Attempt to address some of Client SSL Configuration using javax.net.ssl. Leaving this as draft for guidance and criticism.

Things I don't like or am not sure of:

• My naming of variables and types.
• ClientSSLConfig.FromJavaxNetSsl has odd builder() entry points. Needed to ensure a valid configuration. Any better way?
• Implemented tests but ClientHttpsSpec (and my extension) ignores all tests.

@LannyRipple I changed the secrets from String to Secret so you have to solve some conflicts please 🙂

[987Nabil]

And the ClientHttpsSpec is broken, we had before a config for a website that is no longer available via https. Therefore we deactivated the tests to fix CI. You can remove the @@ ignore to test it. If you can fix the test too, we would be very grateful 🙏

[LannyRipple]

@987Nabil Thanks for eyeballing and the feedback. Will fix these up.

@LannyRipple Looks good to merge! Please re-open when conflicts are fixed and the build is passing. Thank you!

[LannyRipple]

Thanks. Will do when I can find the time for tests (even if just local).
