[PR #1848/c510f26e backport][stable-6] Work on ec2_vpc_subnet related test flake #1870

    Work on ec2_vpc_subnet related test flake
    
    SUMMARY
    As with all things AWS there are no guarantees how fast things will be created.  We currently have a hard coded delay of ~10 seconds to wait for the subnet to be created, while advertising a default timeout of 300s.  If this 10s is exceeded, then we throw a 'NoneType' object is not subscriptable error (because we didn't check that the subnet was actually returned)
    This moves a for-loop over to a waiter.  The "waiter_handler" logic already makes sure we have a total waiting time matching the limits set, even if we wait for multiple things to happen)
