openshift-install: add version string to logs

[crawford]

Including the version in the logs should make debugging a little easier
since we'll definitively know which version of the installer produced
them. This log entry was added under setupFileHook() since it felt
natural to include it as part of the logfile setup: ensure the logging
directory exists, ensure the logfile exists, append the current version.

From the last error, I can see that we hit the rate limit when trying to create a route table association:

HTTP/1.1 503 Service Unavailable

<Response>
  <Errors>
    <Error>
      <Code>RequestLimitExceeded</Code>
      <Message>Request limit exceeded.</Message>
    </Error>
  </Errors>
  <RequestID>c3ba9d60-4778-40bc-93cb-ef5ef0ed04e6</RequestID>
</Response>

But the error reported by Terraform didn't seem to indicate that that was the root cause:

level=error msg="1 error occurred:"
level=error msg="\t* module.vpc.aws_route_table_association.private_routing[3]: 1 error occurred:"
level=error msg="\t* aws_route_table_association.private_routing.3: timeout while waiting for state to become 'success' (timeout: 5m0s)"

Very interesting...
