Gradle build now uses path-based task names

[anuraaga]

#2332 has updated the build to use the folder names in the repository for Gradle task names.

Previously ./gradlew :opentelemetry-api:check is now ./gradlew :api:all:check.

The intent of this change is

• Make commands a bit shorter
• Reduce cognitive load by not having to know the naming scheme that produced tasks previously.

Sorry for the break in muscle memory but hopefully the shorter commands make it worth it :)

Happy hacking!

can we add something to CONTRIBUTING.md about this?

I think previously we might have since we were using custom task names. Now that they're the default, I'm not sure what to add - "Don't worry, we use the default task names"? :P

I just thought I would see how discussions work, mostly. ;)
