[TEST] Allow to run in FIPS JVM (#32607)

* Change SecurityNioHttpServerTransportTests to use PEM key and
certificate files instead of a JKS keystore so that this tests
can also run in a FIPS 140 JVM
* Do not attempt to run cases with ssl.verification_mode NONE in
SessionFactoryTests so that the tests can run in a FIPS 140 JVM
