Specify user:pass from stdin rather than on command line
# Final Release Note
# Description
The current way of specifying username and password, `--userpass xxx:yyy` is undesirable as the command line is visible under /proc. There are couple of alternatives (at least until [#105] is implemented):
- Allow them to be picked up from stdin, e.g., `--userpass -` would read it from stdin, allowing a command line like `echo $userpass | yottadb -run %ydbgui` which ensures that the authentication credentials are visible neither under /proc nor in a shell history.
- Use the mechanism the encryption plugin uses to get the password.
