IMPALA-4874: Increase maximum KRPC message size

The default value for rpc_max_message_size is 50MB.
Impala currently requires support for messages of
up to 2GB. This changes the value of rpc_max_message_size
to INT_MAX for Impala.

Testing:
- Added a test to test_very_large_strings that generates
  a row with multiple large strings. This row requires
  that the RPC framework successfully transmit over
  400MB. This works for both KRPC and Thrift.
  This query operates under the same amount of memory
  as other queries in large_strings.test.
- Tested separately that larger row sizes also work,
  including tests up to almost 2GB.
