Bug Description
The API downloads the entire template before validating it. For a 100 MB file, this causes the API process to use several hundred megabytes of memory. If several requests like this come in simultaneously, the API server will run out of memory.

Validate template size during download
The API downloads the entire template before validating it. For a 100 MB
file, this causes the API process to use several hundred megabytes of
memory. If several requests like this come in simultaneously, the API
server will run out of memory.
