Shell: remove the on-disk index of operations

Browse Source 
Let's get serious. The full index of operations is not sustainable in
the production code. We now only keep the index of operations not yet
in the chain (i.e. the mempool/prevalidation). Operations from the
chain are now only accesible through a block. For instance, see the
RPC:

   /blocks/<hash>/proto/operations
