refactor e2e tests

[maksim-paskal]

Make more reliable e2e test, use same execution logic, as main process. Separate event receiver from main logic, make unit test for event package.

Add new flags:

• -resource.name this flag will ignore Azure resourcename from node, will wait events from this resource
• -exitAfterNodeDrain this flag is needed by e2e tests, this flag wil exits after drain, default false
