- reduce overall size of the structure, store a single required entity
inside of Api object itself.
- tweak internal functions to expect a certain path size
- (kind of a hack) add manual calls to vector<Api>::reserve() as we go over
the current capacity and vector increases it's size times 2.
e.g. for 9 relays, we would allocate space for 32 Api objects
when vector size goes from 16 to 32, after we add 18 Api objects with relay + pulse
- (breaking) json calls on a separate path, don't waste time encoding
a single entity as json object when we can encode more things
