/v1/device/host-config doesn't allow setting of redsocks "log_debug"

[rcooke-warwick]

Right now the /v1/device/host-config endpoint is limited to inly modifying a subset of the redocks configuration fields:

balena-supervisor/src/host-config.ts

Line 35 in 963f43c

const proxyFields = ['type', 'ip', 'port', 'login', 'password'];

A static base header is always used - with "log_debug = off". The only way to modify this property to enable extra logging is to change the redocks.conf file directly. The issue with this is that further PATCH requests to /v1/device/host-config will overwrite this change with the header here again:

balena-supervisor/src/host-config.ts

Line 20 in 963f43c

base {

From my understanding we are deliberately limiting what redsocks configuration options can be modified via this endpoint to try to prevent mistakes being made, which could lead to unreachable devices - for example "local_port = 12345 is set, so that the iptables rules and redsocks port match." - however "log_debug = on" is a safe one to allow - so maybe its worth enabling that?
