Decouple CertificateProvider and adb/idb client intialization

Summary:
Previously CertificateProvider initialized ADB and provided config to IDB. As result, AndroidDeviceManager and iOSDeviceManager indirectly depended on CertificateProvider.

With this diff we:
1. Make idbConfig resemble adbClient.
2. Make AndroidDeviceManager and iOSDeviceManager initialize their own clients
3. Fix server crash when one of the clients couldn't be initialized. The reason for the crash is CertificateProvider.prototype.init which is no longer needed.
