jboss-cli needs to support using PKCS11 (including FIPS mode) keystores/truststores

The cli's SSL configuration should be expanded to support using PKCS11 keystores/truststores. Currently it does not appear to be possible to configure the keystore/truststore type in the jboss-cli.xml file.

This is problematic when the JVM is running in FIPS mode.

The cli throws the following exception on startup:

$ ./bin/jboss-cli.sh

It is possible to workaround the issue by setting the javax.net.ssl.keyStore / javax.net.ssl.trustStore system properties in the bin/jboss-cli.sh file:

JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.trustStore=NONE -Djavax.net.ssl.trustStoreType=PKCS11"
JAVA_OPTS="$JAVA_OPTS -Djavax.net.ssl.keyStore=NONE -Djavax.net.ssl.keyStoreType=PKCS11 -Djavax.net.ssl.keyStorePassword=imapassword"
