Events example using TLS for docker daemon

[3goats]

Hi,

I'm using Boot2Docker on a Mac which uses TLS. How do I configure the certificates for use with the client.

This is what I need to do using the python client.

tls_config = tls.TLSConfig(
client_cert=('cert.pem', 'key.pem'),
verify='ca.pem')

Also I'm getting an error when I run the events exampe.
