* Improve database type inference
Python's DBAPI isn't super clear and homogeneous on the
cursor.description specification, and this PR attempts to improve
inferring the datatypes returned in the cursor.
This work started around Presto's TIMESTAMP type being mishandled as
string as the database driver (pyhive) returns it as a string. The work
here fixes this bug and does a better job at inferring MySQL and Presto types.
It also creates a new method in db_engine_specs allowing for other
databases engines to implement and become more precise on type-inference
as needed.

* Fix rebase issue
* Fix tests
A bug in to_dict(orient="records") in pandas/core/frame.py prevents
datetimes with time zones to be worked with. This works around the
issue in superset by re-implementing the logic of pandas in the
correct way. Until pandas fixes the issue this code should stay.

This closes#1929
* [sqllab] assign types for visualize flow
Somehow when using the visualize flow, the types were not
assigned at all, creating some bugs downstream. This PR attempts to get
the information required based on what pandas is knows and the types in
the data itself.
