Issue #, if available: Making a ton of changes so it works in the SB pipe. Closing out these tickets.

I also tested building locally, and sending to buckets on my AWS account. You can see changes I made in the diff. Thanks

Description of changes:

• Had to change all the names in the build script to be simple-file-manager-for-amazon-efs from efs_file_manager also in the two CloudFormation templates for SB pipe

• Added CFN Nag Meta data tags into external_resources.json also I modified the build-s3-dist.sh just to not use AWS s3 Sync when running through SB pipe

• Adding buildspec.yml file so that the SB pipe can call our build script. Tested that out

• Adding ignore fields to viperlightignore so SB pipe builds

Just to note I tested this in the SB pipe after build, and also tested on a local bucket in my account to make sure things can build in both areas fine! 👍
