NE-1324: E2E tests for Assume Role in Shared VPC Cluster

New e2e_sharedvpc E2E test package which contains the E2E tests for
AWS shared VPC clusters. These tests are isolated because of their
unique requirement for a specific cluster configuration. A common
package has been added to support both types of E2E tests. The new E2E
test validates the use of `spec.provider.aws.assumeRole.arn` in a shared
VPC cluster.
