Add asset management scripts

These provide an easy way to create assets to be used by bots,
eg. Android SDK.

To create an asset:
$ infra/bots/assets/assets.py add android_sdk
(adds scripts in infra/bots/assets/android_sdk)

To upload a new version of an asset:
$ infra/bots/assets/android_sdk/upload.py -t $ANDROID_SDK_ROOT
(uploads Android SDK to GS, writes a version file)
$ git commit
$ git cl upload

To download the current version of the asset:
$ infra/bots/assets/android_sdk/download.py -t ../tmp
