reducing cURL dependency size

[missinglink]

Heya,

I've been looking at reducing the size of images generated with this lib and found that 105M of the total 323M image size is being taken up by the curl-7.77.0 directory:

323M    /
105M    /code/node_modules/aws-lambda-ric/deps/curl-7.77.0

Within that dir there seem to be a bunch of files not required at runtime:

3.3M    /code/node_modules/aws-lambda-ric/deps/curl-7.77.0/autom4te.cache
1.3M    /code/node_modules/aws-lambda-ric/deps/curl-7.77.0/config.log
1.3M    /code/node_modules/aws-lambda-ric/deps/curl-7.77.0/configure
6.7M    /code/node_modules/aws-lambda-ric/deps/curl-7.77.0/docs
25M /code/node_modules/aws-lambda-ric/deps/curl-7.77.0/lib
3.3M    /code/node_modules/aws-lambda-ric/deps/curl-7.77.0/projects
4.8M    /code/node_modules/aws-lambda-ric/deps/curl-7.77.0/src
56M /code/node_modules/aws-lambda-ric/deps/curl-7.77.0/tests

I'm assuming it's not safe to just delete /code/node_modules/aws-lambda-ric/deps/curl-7.77.0? ... but presumably we could ditch some dirs such as curl-7.77.0/tests and the cache/log/configure/docs etc. files?

The following command helps reduce the image size significantly:

# https://github.com/aws/aws-lambda-nodejs-runtime-interface-client/issues/28
RUN rm -rf \
  node_modules/aws-lambda-ric/deps/curl-*/autom4te.cache \
  node_modules/aws-lambda-ric/deps/curl-*/config.log \
  node_modules/aws-lambda-ric/deps/curl-*/configure \
  node_modules/aws-lambda-ric/deps/curl-*/docs \
  node_modules/aws-lambda-ric/deps/curl-*/projects \
  node_modules/aws-lambda-ric/deps/curl-*/tests \
  node_modules/aws-lambda-ric/deps/curl-*/README

33M /code/node_modules/aws-lambda-ric/deps/curl-7.77.0

This one seems pretty bonkers... Could it not just use a pre-installed libcurl and fail if its not available?

This is fixed in https://github.com/aws/aws-lambda-nodejs-runtime-interface-client/pull/70.
