Licensing

I think this change is autogenerated, but do we know why this license is being removed? I think boltdb is still being used

[tinnywang]

BoltDB was removed in #113, specifically in 7ac5bce when updating to a newer version of docker/libkv. docker/libkv switched from BoltDB to BBolt in docker/libkv#202.

I didn't run make generate in #113 so BoltDB wasn't removed from the license until now. BBolt wasn't added because it's from go.etcd.io, and the license script currently only covers github.com and golang.org packages.

To clarify, I think aws/amazon-ecs-agent#4349 is testing against 8d91625 commit, is that right? Could you run a test with 4e2f3f2 as well?

[tinnywang]

Updated aws/amazon-ecs-agent#4349 to test against 4e2f3f2.

Thanks for making this change! Also seems like session is no longer used in favor of config (link). Mind also including this in the PR description just so we can reference back to this for any future occurrences where we're migrating over to aws-sdk-go-v2?
