docs: remove focus on Druid in README.md (#9184) 

The text in the README seemed overly Druid-centric at this time. While
originally (3-4 years ago) Superset was heavily focussed on druid, it's
just not accurate anymore. Druid is just one of the databases that we
support and docs should reflect that.

Apache Druid (Incubating)!
------
On top of having the ability to query your relational databases,
Superset ships with deep integration with Druid (a real time distributed
column-store). When querying Druid,
Superset can query humongous amounts of data on top of real time dataset.
Note that Superset does not require Druid in any way to function, it's simply
another database backend that it can query.
Here's a description of Druid from the http://druid.io website:
*Druid is an open-source analytics data store designed for
business intelligence (OLAP) queries on event data. Druid provides low
latency (real-time) data ingestion, flexible data exploration,
and fast data aggregation. Existing Druid deployments have scaled to
trillions of events and petabytes of data. Druid is best used to
power analytic dashboards and applications.*

The native Druid connector (behind the ``DRUID_IS_ACTIVE`` feature flag)
is slowly getting deprecated in favor of the SQLAlchemy/DBAPI connector made
available in the ``pydruid`` library.
