GCE: Remove resource Get function calls from Create functions

**What this PR does / why we need it**:
Consistency. This PR removes the GetXXX from the CreateXXX functions of the GCE cloudprovider. Consumers (specifically the ingress controller) will need to call the Get resource funcs separately when updating their vendored versions. 

**Release note**:
```release-note
NONE
```
