TLS Toolkit doesn't support -outputDirectory property in all modes

TLS toolkit has 3 modes:

1. standalone
2. server (host a CA authority server)
3. client (remotely interact with CA authority server)

There is an -o option to dump all artifacts (config, keystore, truststore) in a dedicated directory (default is . ). However, it's not a supported property for server and client mode.

This is most useful for 'client' mode. When running on a remote workstation to create new certs signed by a NiFi CA authority, quite a few files are saved. If I need to generate multiple certs for multiple people I would have to manually move files out of the way (otherwise they are overwritten).

Expected: add o/-outputDirectory to the client mode (maybe server too).
