Issue 203: Update the truststore/keystore for stream-tests (#301)

* Update the stream-tests truststore/keystore to refer to pekko-remote

The same truststore/keyspace as the one generate with the Makefile at remote/src/test/resources is used here"

* Revert "Update the stream-tests truststore/keystore to refer to pekko-remote"

This reverts commit 7bab689bb6257e80d2bd8cdff2b8a715bb08c619.

* Issue 203: Update keystore/truststore for stream-tests:

Note that no SAN extension file is used in this case. Therefore the verify hostname code looks at the CN= instead of the subjectAltName field.
I've added a Makefile here to make it easier to regenerate this in future: just delete the trust/keystores and run 'make'

* 203: Add comment explaining new Makefile
