Use the FC api /entropy endpoint to configure the virtio-rng device

[0div]

Description

virtio-rng front-end driver should already be compiled in in the kernel, based on the config.

this go code is equivalent to running:

curl --unix-socket $socket_location -i \
    -X PUT 'http://localhost/entropy' \
    -H 'Accept: application/json' \
    -H 'Content-Type: application/json' \
    -d "{
        \"rate_limiter\": {
            \"bandwidth\": {
                \"size\": 1000,
                \"one_time_burst\": 0,
                \"refill_time\": 100
            }
        }
    }"

I'm currently working on solving a code-interpreter same seed problem that will validate this or not.

The test should be here, otherwise it's possible to deploy broken version and find out too late
