AWS Lambda Runtime outdated

[genghis-yang]

From https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html, I can see many new runtimes are not supported by dpl now. Like nodejs14.x, dotnetcore3.1, and provided.

When I want to deploy some executable binaries to AWS Lambda, I got such error info in log:

...
Unknown value: runtime=provided (known values: nodejs12.x, nodejs10.x, python3.8, python3.7, python3.6, python2.7, ruby2.7, ruby2.5, java11, java8, go1.x, dotnetcore2.1)
failed to deploy

So it's time for an update.

I saw PR #1236 added a new runtime for lambda provider. But there are still a lot missed.
So I'll create a new PR to add all missed runtimes.
