Improved the ReadHttpHeaders function, by making sure that a chunk is read fully from the stream (the number of bytes read by the Stream.Read function can be less than the number of bytes requested, so we need to continue reading until the required number of bytes is read)

Added "VM.pool_migrate" to the list of tasks suitable for meddling actions.
Removed the usage of MeddlingActionTitle other_config key, because it wasn't working as intended for two reasons:
- If XenCenter starts an action that does multiple async api calls, so multiple tasks, the action's title is assigned to all tasks as MeddlingActionTitles, so the second XenCenter instance would create multiple meddling actions with the same title.
- When a second XenCenter instance tries to see if a task is suitable for a meddling action, the MeddlingActionTitle is not yet present in the task's other_config, so the task is ignored in most of the cases.

Added an extra parameter to the CreateVmFastAction constructor, which is used to specify whether to set the VM's property IsBeingCreated. In order to set this property, we need to wait for the newly created VM to appear in the cache. But we cannot do this in the action test, because the cache is not being updated. Therefore the action needs skip this step when running from the tests. The IsBeingCreated property is only used in the UI, to refresh the PVS tab after the VM is created, so the accuracy of the action test (CreateVMFastActionTest) is not affected by this change.

* [CA-233454] PVS tab doesn't show a new VM when it's created
Refined the rules for not adding a VM to the table, if it is a template (thus not_a_real_vm), and it has the __gui__ prefix (thus hidden), we still add it, but hide it.
When its name is changed (to remove the __gui__ prefix), we update its name and re-calculate whether it should be visible (in the case of a new VM this will be true once the __gui__ prefix is gone). Also resort the table if a node changes from hidden to visible, because it appears as an addition to the table.

* [CA-233454] Update when the VMs are shown in the PVS list
New observable property IsBeingCreated for VMs, set to true when they're made a hidden object, and false when they're removed from hidden objects (both in CreateVMAction). In the PVS Page when this is set to false, we re-evaluate whether a VM can be shown. This means that new VMs show here at the same time they're added to the tree (only different is tree refresh time), instead of far earlier (and before their networks were added).

The resume on server uses the CrossPoolMigrateCommand to implement the migration of the VM to the desired host. Before this change that command had no support for resuming a VM after migrating it, so the VM was not resumed. With this change, the CrossPoolMigrateWizard can take an optional (default false) parameter to restart the VM after migration. When this is true, the migrate action becomes a MultipleAction, first migrating and then restarting the VM.

We have some new RRDs - read, write, read_latency and write_latency. This adds support for them by adding a friendly name and using it to display them. It also adds some filtering (see GraphHelpers.cs) because for backward compatibility io_throughput_read and io_throughput_write (which differ from read and write only in scale) are still available, but shouldn't be displayed in XC. If the new read or write are available, we filter these old datasources out.

Normally, a heartbeat is done every 15 seconds by getting the server time, and starts as soon as connection to host is established, but if an error occurs XC retries once more in another 15 seconds before actually closing the connection to the host.
Now, if a 407 Proxy Authentication Required error occurs on the initial heartbeat then XC does not retry again in 15 seconds; it will close the connection immediately. The disconnection was instant to up to 2 seconds, depending on time taken to get server time (testing with FreeProxy was ~instant and CCProxy was ~2 seconds). This is only a work-around, as the exact reason for this behaviour is still unknown.
