<code>PasswordClientAuthenticator</code> provides a fixed username/password 
authentication response when connecting to any Ghidra Server or accessing
a protected PKI keystore.  The use of this authenticator is intended for
headless applications in which the user is unable to respond to such
prompts.  SSH authentication is not currently supported.  Anonymous user
access is not supported.
<p>
If a PKI certificate has been installed, a password may be required 
to access the certificate keystore independent of any other password which may be required
for accessing SSH keys or server password authentication.  In such headless situations,
the PKI certificate path/password should be specified via a property since it is unlikely
that the same password will apply.
