Fix mode/comp params so parameter overrides work (#2085) PR adds capability to override parameters when specifying mode and compression. In order to do this, I add functionality for creating a deep copy of KNNMethodContext and MethodComponentContext so that we wouldnt overwrite user provided config. Then, re-arranged some of the parameter resolution logic. Signed-off-by: John Mazanec <jmazane@amazon.com> (cherry picked from commit 270ac6a52f2ff9cc9cfa58dbd65333b21f925048)
