Update default engine to FAISS (#2235)

Since faiss supports more features than nmslib, and, we had seen
data points that there are more number of vector search
users are interesed in faiss, we will be updating default
engine to be faiss. This will benefit users who preffered
to use defaults while working with vector search.

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.
