Add batch generation to OTAGUI.
Batch generation of OTA packages is a important feature
requested by googler and partners: please refer to go/ota-dashboard-doc.
Given n incremental source builds and m target builds,
batch generation will generate n x m OTA packages in total.
If n=0, full OTA package will be generated.
The front end will be taking in the source/target lists and send the
request to backend one-by-one.
Test: mannual tested.
