Add cert based auth provision for proxy in this SDK

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

• This SDK does not support cert based auth for the proxy. This request call is creating new brand new call every time - and not using KustoClient_session.
• And it takes proxy but has no option to give cert and verify keys to provide cert based auth.

Describe the solution you'd like
A clear and concise description of what you want to happen.

• Add sessions ioption for cert and verify/cacert like:
  self.client._session.verify
  self.client._session.cert
  with proxy as session or set_proxy()

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

• Used username and password based auth for the proxy instead of cert based auth.

#588 will make the cloud info use the same session.

From there, you can use the _session field to set your parameters.
In the future we may give a more streamlined way to do it.

Sounds ok?
