Add support for NDK install/update #90
Description
What would you like to be added
I would like to have ability to specify NDK version in ci config.
Why is this needed
It's need because I need to manage own docker image with up-to-date NDK.
* What went wrong:
Execution failed for task ':app:stripStageReleaseDebugSymbols'.
> No version of NDK matched the requested version 21.0.6113669. Versions available locally: 20.1.5948944
