This is related to this issue: https://issues.jboss.org/browse/AEROGEAR-2913.

The way currently mobile ci/cd works is to ask developers to create the build crendentials via openshift secrets, and the use the `singApk` plugin to sign the apk manually.

However, at the moment, most of android apps will have the keystore file checked into the repo, and developers just need to provide the password during build time and then gradle will handle app signing automatically during build time.

I think we should support this mode as well in the mobile ci/cd.

In order to support this, we can ask developers that if they already have the keystore file in the app repo, they can just create secrets for the keystore passwords. Those passwords will be injected during build time. Developers can then pass them to the gradle command in the Jenkins file and use gradle to sign the file.
