Prod 1625 remove autotuner support

[gorskysd]

Delete the Autotuner/Predictions components of the library.

Overview of changes

• Change "autotuner/products" endpoint call to "projects/products". (See corresponding backend PR)
• Delete all downstream occurrences of "autotuner" endpoint calls. Most functions are delete entirely. For a few, only the autotuner fork is deleted.
• Clean up documentation to remove presence of autotuner and "aws-emr" support
• Remove the "preference" option from configuration (e.g. ECONOMY), which was autotuner specific
• Delete autotuner tests. Unfortunately this was all of the test, of which there were few.

rubber stamp because its mostly code removal. PR is just generally too large to do a good review.

JK this needs a library version bump, probably a MAJOR version bump because this is removing functionality
