This commit switches to a stream based nippy
compression/serialization. This has the benefit of being able to stop
serialization once the threshold for cache size has been reached.

Fixes #7479

Previously we would serialize rows as strings and use that as an
estimate for how big the cache would be. This commit changes that to
use actual compressed bytes to determine size.

Only include a CSV attachment for pulses when XLS is not selected

Previously we would always include a CSV attachment when there were
more rows/columns than would be included in the table. This ended up
being redundant for users that would prefer an XLS attachment and have
indicated that the pulse should include an XLS attachment. This commit
will only not attach a CSV if the user has select an XLS attachment
for that pulse.

Fixes #7302

Add better error messages to loading GeoJSON files

Previously the only error message was a schema validation failure. The
same error would be given for an unreachable host, unparsable JSON,
bad URL etc. This commit attempts to separate that out and provide a
better message in the failure case.

Fixes #8793

Fix test checksum test failure on MySQL [ci drivers]

The newly added checksum tests fail when running on MySQL in
Circle. The MySQL tests include a secret key for encryption which are
used when computing the checksum. Because of that encryption, the
checksum string is different every time (it must be decrypted before
compared). The test isn't covering the encryption code but is only
concerned with ensure the datastructure hashes consitently. This
commit uses a `with-redefs` to set that secret key to `nil` so that
encryption won't be used on those two tests.

Ensure consistent ordering of maps/sets when hashing metadata

This commit will ensure all hashes and sets are ordered before
serializing them to JSON and hashing that string. This will prevent
surprising behavior when the number of items in a map reach 9 or if
the order of elements changes between machines or JDK versions.

Fixes #8826

Dropped tables should appear in a schema's data browse page

When the database had only a single schema, the dropped tables were
being hidden correctly. When multiple schemas were present, viewing
those tables their the schema route caused the inactive tables to
appear in the result.

Ensure queries to compute metadata include user information

When saving a question and the included metadata is incorrect or
different we will execute another query to compute that metadata. This
commit adds the `:info` map needed to include the user and query hash
information we use in the SQL remark.

Fixes #8825

Change query result hashing to convert integers to doubles first

When the FE returns the query result metadata, any integer values will
be converted to a floating point number. Those doubles hash different
than the original integers which causes the hashes not to match and
the query to be reran when saving the question. This commit just
converts the integer to a double before computing the hash.
