VOL-2395: Defer creation of EVTO and pyvoltha that does not cache

Defer the creation of the EVTO object and also delete if it exists
This prevents lingering vlan configuration that may be left after a
device disable/enable preventing passing traffic.

Also use newer pyvolthat that does not cache old TP values.
