[ Merge of http://go/wvgerrit/87905 ] Protobuf parsing of the provisioning message has been centralized in certificate_provisioning.cpp since it will be invoked from multiple locations. This will also ease maintainability of the code. Bug: 142731300 Test: android unit/integration tests Change-Id: Idebf6b0145b317698559cac1cf18a3a0b98315ad
