raft: increase raft notify buffer. (#6863)

Browse source 
* Increase raft notify buffer.

Fixes https://github.com/hashicorp/consul/issues/6852.

Increasing the buffer helps recovering from leader flapping. It lowers
the chances of the flapping leader to get into a deadlock situation like
described in #6852.
