Hotfix for dbapi2 issue

This hotfix implements a workaround for an issue in the underlying Python dbapi2 library which cannot handle timestamps with timezones but not microseconds. This issue affects the base_historian and sqlite historian in VOLTTRON.

VOLTTRON 3.0

3.0 sees major changes to the internals of VOLTTRON making it more flexible, manageable, and secure. VOLTTRON’s driver and data historians can be more easily customized to suit your needs. In addition, a beta management interface has been implemented to allow visibility into deployments. Communications have been re-implemented to use the VOLTTRON Interconnect Protocol (VIP) to secure communication within and between platforms.
