Enhancement: More control over thumbnail processing.

[ghost]

Brief description

Add specific control for processing of thumbnails.

Description

Improve control over processing of thumbnails using profiles to indicate hosts and tasks.
Fixes a bug (Should fix Issue #2843), handles files with arbitrary size processing in through setting max_int as an FFMPEG flag, as well as handling video files through FFMPEG specifically, and image files through OpenImageIO utility.

Additional info

Some refactoring is done to check for specific file format within the representation in order to specify which tool is used for the thumbnail creation (to reduce probability of errors).

• First of all, do not crash if oiio is not supported.
• Secondly, separate the extraction logic using ffmpeg and oiio into their separated methods. They should return if were successfull and should not crash if were not (thumbnail is not reason to crash publishing?). Failed extraction should cause warning log.
• Using extensions would be endless goal. Thus I recommend that you can check if oiio supports a file just by simply try to read information about it. If can't read their information then you can try convert it using ffmpeg.

from openpype.lib import oiio_is_supported, execute

thumbnail_created = False
# Try use ffmpeg when oiio is not supported (for cases when oiio tool is not available)
if not oiio_is_supported():
    thumbnail_created = self.create_thumbnail_with_ffmpeg(src_path, dst_path)
else:
    # Check if file can be read by oiio
    args = [
        oiiotool_path, "--info", "-i", src_path
    ]
    returncode = execute(args, silet=True)
    
    # If input can be read by oiio then use oiio method for creation otherwise use ffmpeg
    if returncode == 0:
        thumbnail_created = self.create_thumbnail_oiio(src_path, dst_path)
    else:
        thumbnail_created = self.create_thumbnail_with_ffmpeg(src_path, dst_path)

# Skip rest of process if thumbnail was not created
if not thumbnail_created:
    return

# Rest of plugin logic

Thank you @iLLiCiTiT I appreciate the thorough reply! Will get on that right away!

Some comments... Couldn't test it currently because of unrelated bugs, but otherwise it looks ok.
