This function is generator.
Arguments:
filename - Name of file which exists in local filesystem
Keyword arguments:
content_type - Filetype. By default - None means auto-detect.
max_age - Cache control. How long browser can keep this file on disk.
By default - 30 days
Set to 0 - to disable caching.
Example 1: Default use case:

Example 2: Disable caching:
await resp.send_file('static/index.html', max_age=0)
Example 3: Override content type:
