Disallow DES for SSL connections

Older OpenSSL versions include DES-CBC3-* ciphers when specifying the
HIGH group of ciphers. Removing potentially weak ciphers from the list
of allowed ciphers ensures only strong ciphers are considered for SSL
connections....

Start instance after creating snapshots for export

This restores functionality lost in commit 387794f8. Found during
tests using QA scripts. An instance should be started after it
has been temporarily shutdown for an export.

Use import/export magic for backup/import and inter-cluster moves

This should prevent bugs in our code from accidentally overwriting
disks.

Disable compression for all intra-cluster imports/exports

Tests have shown that usually we're CPU-bound for intra-cluster
imports/exports. Disabling compression will help with this.

Some versions of OpenSSL, depending on the build options, also
compress transparently. This will need further work in Ganeti....

qa_rapi: Test inter-cluster instance move script

This test moves an instance on the same cluster and, if successful,
moves it back. While not testing a real move between two clusters,
this is certainly better than nothing.

import/export daemon: Add support for a magic prefix

This “magic” value will be used to ensure that we don't accidentially
connect to the wrong daemon (e.g. due to a bug), comparable to DRBD's
per-disk secret. Just depending on the SSL certificate isn't enough...

import/export daemon: Simplify command building

Instead of appending strings, stage parts in a list. Building the "dd"
command is moved to a separate function.

import/export: Validate remote host/port

The hostname and port received from the remote cluster should
be validated, just in case.
