nodeSelector support during deployment for mixed node clusters

[mikenorgate]

What would you like to be added:
Add ability to specify nodeSelector during deployment

Why is this needed:
When deploying into a cluster container a mixture of Windows and Linux nodes I would like to be able to specify a nodeSelector with a value of kubernetes.io/os: linux to make sure the submariner pods are scheduled to the correct nodes

This might solve the use case: submariner-io/enhancements#149

[mkolesnik]

to make sure the submariner pods are scheduled to the correct nodes

Which pods do you mean exactly?

Or are you simply trying to limit all submariner pods to Linux nodes only?

Idea is to implement this through a generic option to take a yaml file as input, probably take Submariner CR as input yaml with all fields missing from yaml filled up as per current default.

Isn’t this done @vthapar?
