sshtunnel not working. keeps showing ERROR | Password is required for key about sshtunnel HOT 1 OPEN

this seems to be caused by this line:
https://github.com/pahaz/sshtunnel/blob/master/sshtunnel.py#L1314

which incorrectly emits an error message, when this message should be classed as a warning.

I have successfully monkey-patched this code to emit a warning, which I can then ignore, in my own code. There are multiple threads about this issue in various forums, and the general advice seems to be "just ignore it, it's not an error, your code will keep working" ... I beg to differ, it literally is an error, and that line is where it's thrown.

I mention this in the hopes that line can be changed to logger.warning ... but in the mean time, if you'd like to keep using this library as-is, you can monkey-patch the read_private_key_file function in sshtunnel.py.
