"You seem to be lost" message for TuxOE

Hello,

A build team member from Oniro project (pavel.zhukov@huawei.com) got a message "You seem to be lost." (according to him it was stuck in provisioning). It was a tuxoe Oniro build. After further insight seems he tried to use 'tag' in the .json file instead of 'branch'.

I have two propositions here

• document the correct json schema
• introduce validation for the schema prior to submitting the build

Also, tag support would be good :)
