SNOW-560911: Unused dependencies as of v1.6.7

[veltman]

The package.json for the Snowflake connector includes a large number of dependencies and devDependencies that don't appear to be used anywhere in the codebase or necessary as peerDependencies:

http-signature
https-proxy-agent
json-schema
jsprim
lodash
oscp
follow-redirects
insert-module-globals
vinyl-buffer
vinyl-source-stream

Is there a reason why these dependencies are still required?

Additionally, these two packages are listed in dependencies but are only used in tests, so seem like they should be in devDependencies:

mock-require
test-console

Yes, I double that. We pinned snowflake-sdk to 1.6.1 long time ago to avoid unnecessary dependency bloat.
