7. SOLR-5776,SOLR-9068,SOLR-8970:(hossman)

Refactor SSLConfig so that SSLTestConfig can provide SSLContexts using a NullSecureRandom to prevent SSL tests from blocking on entropy starved machines.
SSLTestConfig: Alternate (psuedo random) NullSecureRandom for Constants.SUN_OS.
SSLTestConfig: Replace NullSecureRandom w/ NotSecurePsuedoRandom.
Change SSLTestConfig to use a keystore file that is included as a resource in the test-framework jar so users subclassing SolrTestCaseJ4 don’t need to preserve magic paths.
