[ASTERIXDB-2137][ING][API] Prevent REST API hang on stopped feeds

- user model changes: no
- storage format changes: no
- interface changes: no

Details:
1. Due to the ActiveEventListener change, current implementation will
try to issue stats request to stopped feed and never get back. This is
fixed.
2. Now we only request stats for active feeds.
3. When feed stopped, the cached stats will be reinitialized. This is to
prevent users see the previous active stats after immediate start after
stop.

> GET on feed status REST endpoint localhost:19002/admin/active goes into an endless loop and never returns a result if any feed successfully completes or is stopped by the user.
> After the following AQL "curl http://127.0.0.1:19002/admin/active" hangs forever:
> {code}
> drop dataverse test if exists;
> create dataverse test;
> use dataverse test;
> create type TestType as open {
>         "id": int8

> create dataset TestDataset(TestType) primary key id;
> create feed TestFeed using socket_adapter

>     //type of the record

>     //format of the record
>     ("format"="adm")

> connect feed TestFeed to dataset TestDataset;
> set wait-for-completion-feed "no";
> start feed TestFeed;
> stop feed TestFeed;
