Remove blockdev_export RPC

This RPC call is no longer used, as for intra-cluster instance moves the
import/export daemon is used too.

Optimize dd parameters for instances moves

Benchmarks have shown that increasing the buffer size and disabling
synchronous output increased the throughput by about 10MiB/s, so make
those parameters the default.

Note that not using sync for output doesn't increase the risk of data...

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.

Use cluster variable consistently

The cluster object is already retrieved from the configuration, so use
it consistently in LUInstanceMove.CheckPrereq().

Fix expectation of the htools wrapping

With the addition of hsqueeze, htools obtained a new personality.
Additionally, the longer htool name also changes the line wrapping of
the descriptions. Adapt the expectation accordingly.

Add test for hsqueeze compression

In this example cluster, there are 6 nodes with
capacity for 4 instances each, holding a total
of 8 instances. So even after turning off 2 nodes
and rebalancing, every node still has capacity for
2 instances.

Add hsqueeze planning for compression

Add a new htool, hsqueeze, for dynamic power management. This
commit only implements the first useful part: plan (but not
executing) taking nodes offline nodes still keeping within the
resource limit.
