Add --rollout-percentage to sz deploy android (#1019)

This PR adds the `--rollout-percentage` to `sz deploy android`: The percentage (between 0.0 - 1.0) of the user fraction when uploading to the rollout track (setting to 1 will complete the rollout). Additionally, this PR adds the parameters to `stable.yml` (default: 0.2) and `beta.yml` (default: 1.0).
