[HCS Analysis] Video generation API enhancements

[rodichenko]

Background At the moment, HCS Video generation API generates output files to the predefined destination (based on the input .hcs image and the selected well / field). For two or more simultaneous requests for the same well / field, API will write files to the same destination. We need to change that behavior - each request should write output file to the unique (i.e., request-dependent) folder / file.

Approach For each request, API shall generate a unique identifier (UUID) and store the output video file to the UUID-dependent directory, e.g. /some-predefined-output-folder/<REQUEST_UUID>/well1seq1plane1.mp4
