Refactor e2e test suite to simplify new tests addition

[Danil-Grigorev]

We have multiple instances of semi-duplicated suites across e2e. We need a builder for suite, which will allow us to construct:

• If it is GKE based execution
• Is VSphere involved
• Is this a local run
• Is it isolated execution using sslip.io or not
• Any additional modifications to network, providers, etc.

This will reduce boilerplate and streamline additions to the suite and supportability for the existing ones, eliminating problems like #586 or difficulties with additions like #585
