Embeded -> Embedded

Switch to the redshift depndency that doesn't embed the Amazon SDK 

The Redshift dependency used previously vendors quite a few
dependencies that we already include in Metabase. By using the
non-embedded Redshift dependency, we can cut about 8 MB in duplicate
JARs and classes.

The embedded Amazon SDK dependency also manipulates the classloader in
a way that triggers warnings on Java 9. This also avoids those warnings.

Fix docker build image script  [ci skip]

This commit changes how the word frequency and cost data is
represented in memory. Previously this data consumed about 7 MB on all
Metabase instances. This commit lowers that memory to roughly 1.5
MB. The primary change is storing the hash of the strings in a
primitive integer array instead of the strings themselves. It also
stores the cost in a correlated primitive double array, saving space
there as well.

Fix bug causing test email pulses to fail

When test pulses are sent out their channel_types are strings not
keywords which caused the multimethod lookup in the pulse code to
fail. This commit adds a unit test that covers our pulse test
capability and ensures channel_type fields are keywords before
invoking the multimethod.
