src: add POST cache/delete method

Add API REST method to delete cache contents.

Resquest payload structure:
{
    'images': ['windows.img', 'linux.img']
}

The client will try to delete as many images in cache as available
with names matching the list of filenames in the 'images' field.

Resquest response structure:
{
    'cache': [
        {'name': 'windows.img', 'size': 2432370213, checksum: '5d4dcc677bc19f40a647d0002f4ade90'},
        {'name': 'linux.img', 'size': 243234534213, checksum: '3eb22f888f88a55ad954f55644e1192e'}
    ]
}
