Problem: All members in group goes in ERROR STATE when new member joins and
certification database is big

Scenario (slow machine with heavy load):
1. Start 3 server (MEMBER_1, MEMBER_2, MEMBER_3)
2. Wait for all members to be ONLINE
3. Start heavy load on MEMBER_1 (wait for 5 to 10 minutes) (MEMBER_2 and MEMBER_3 receives data slowly.)
4. STOP, START MEMBER_3
5. MEMBER_1 and MEMBER_2 goes offline

Description: When new member joins server, certification database can be big.
Certification database is transferred with View_change.
If packet size(View_change) is greater then 4MB, GR stops and goes in error state.

Resolution:
Applier thread will be initialized with slave_max_allowed_packet, which default
size is 1GB.
