app/vmalert/datasource: reduce number of allocations when parsing instant responses (#6272) 
Allocations are reduced by implementing custom json parser via fastjson
lib.
The change also re-uses `promInstant` object in attempt to reduce number
of
allocations when parsing big responses, as usually happens with heavy
recording rules.

```
name                                old allocs/op  new allocs/op  delta
ParsePrometheusResponse/Instant-10     9.65k ± 0%     5.60k ± 0%   ~     (p=1.000 n=1+1)

```
