Removes the legacy networking stages, superseded by 2-networking.
**Breaking Changes**
```upgrade-note
`fast/stages/2-networking-legacy-a-simple`: The stage is being removed, and superseded by the `2-networking` FAST stage, introduced in #3435
`fast/stages/2-networking-legacy-b-nva`: The stage is being removed, and superseded by the `2-networking` FAST stage, introduced in #3435

```
Additional changes:
* align vpc-connector interface to Cloud Functions
* split managed and unmanaged resources into separate files, this makes
easier to introduce further changes
* add support for contexts
* move `vpc_connector` variable to variables.tf for Cloud Functions
* remove `create` from `vpc_connector` in Cloud Functions as it was
sharing the meaning with `vpc_connector_create`
