Description

In doing some research for a client on LWTs, I found that once we start pushing a node hard enough, with enough LWTs, decompressing the data in the paxos table takes up quite a bit of time. I've attached an SVG flame graph showing about 10% of time is spent in LZ4_decompress_fast in queries hitting the paxos table. 

We should allow the user to modify the compression settings on this table.
