The patch sets format for spaces with sysview engine.
This is done due to following reasons:
  1. Since an SQL view looks into underneath space's format, set
     it for spaces with sysview engine. Before the patch, spaces
     with sysview enginge didn't have its own tuples and hence
     didn't need to have a format.
  2. To use sysview engine to deal with SQL views. This will allow
     to use sysview machinery to query SQL views from Lua land.
