Optimize dd parameters for instances moves

Benchmarks have shown that increasing the buffer size and disabling

Use import-export daemon for intra-cluster moves

This unifies the inter- and intra-cluster moves and the backup code, so
less code needs to be maintained.

Also fix failing tests for LUInstanceMove by following the code changes
in the tests.
