Alongside with the generated proto file, the aconfig_declaration now also outputs a text file that lists aconfig flags and values of its corresponding proto file, in the format as shown below: ``` my.flag1=true my.flag2=false ... ``` To prevent confusion between the preexisting proto file and the newly introduced text file, the change also renames the variables of the proto file from `intermediatePath` to `intermediateCacheOutputPath` and likewise. The utilization of the generated text file will be done in the child changes.
