Fix async test race conditions, part II

Add a noop `-init-driver` function to `metabase.driver.google`

Remove ^:always-validate metadata

Add more ordering to pulse_channel_test results

The data comes right out of the database without an order applied so
occasionally there are transient failures due to the order being
different. This just dumps the data in a set since the order isn't important.

A warning is currently shown as we assume that namespace is a
driver. It's used by driver code but is not itself a driver. Added a
noop function so it won't output that warning.

Code cleanup 

Fix potential race condition where the job gets cleaned up too soon.

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.
