Add Nokia SR OS support (draft)

[jbemmel]

This is a tentative PR to add support for Nokia SR OS through an additional NAPALM driver

It is not intended to be merged just yet - the referenced napalm-sros version 1.0.1 isn't available yet - but this is just to give the project a heads up on what we are planning to contribute, and to have a chance to receive any feedback/comments/concerns

• Add "Nokia SR OS" platform choice
• Add napalm-sros and bcrypt as dependencies
• Add Nokia Bcrypt password encoding

It would be great if you added some template examples as well...

Am still working on the device configuration templates, but I did have a sample virtual lab that may be of interest

If somebody has interest, I have installed the Napalm SROS driver added Nokia SROS with NAPALM drive sros.
At this moment I can make config diffs and commits. Only issue is that Error reporting if config is not correct, Is not handled as expected. I will dig into this.

At this moment I have a pretty decent template with policy-options / prefix-list / bgp peers /groups/ and communities. Will share this one if its throughly tested.

@jbemmel I had created a small change to the driver, because it always detected merge differences: matching (ex)[]
