RFR: 8366364: Address inconsistencies in SSLParameters object returned by SSLConfiguration#getSSLParameters() call [v4]

[Artur Barashev]

> We need to address the following inconsistencies in SSLConfiguration#getSSLParameters() call:
> - For the signatureSchemes we return only what's been set by the user, the default values are not being returned like for other SSLParameters.
> - namedGroups return value is not being filtered against algorithm constraints, unlike other SSLParameters.

Artur Barashev has updated the pull request incrementally with one additional commit since the last revision:

  - Use better logging method
  - Remove now unnecessary null check for config.signatureSchemes
