Let me know if Elastic APM AWS Lambda extension should be something else

[jlvoiseux]

Thank you for this ! I tend to use Elastic APM Lambda Extension, as the name of the Go package is apm-lambda-extension. It is also the name widely used in our first blog post on the subject. However, I am aware this convention is not strictly applied everywhere, which can make things confusing.

Thank you for this, LGTM, aside from the name of the extension

[simitt]

LGTM except for the last bit with the naming. Please wait with merging it in until @gtback also gave it a quick review.

@stuartnelson3 I actually just run make but the license wasn't updated. Can you ensure to also include the update into the regular make and build process?
It looks like you only hoooked up the check that the license is up to date with Jenkins.

[simitt]

Please also rename LICENSE to LICENSE.txt

Thanks Stuart!
