Allow setting the VIF backend for a network

If, on a network, other_config:backend_vm is set to the UUID of a VM, this VM is
used for the VIF backends (netback) of any VIFs on the network.

This is useful for internal networks (only), since the key is set on a network
rather than on a PIF.

CA-99726: Don't make VM.provisions wait in line

VM.provision will run after a template has been copied or cloned, so we
don't need it to wait in line behind other VM.copy or VM.checkpoint
tasks.

CP-2190 for PR-1221: SR alerts for hosts can be configured on the SR now.

To reduce the effort of configuration, whereas previously it was
necessary to configure throughput alerts for an SR on each host
individually, now it is possible to set up a per-host SR throughput
alert for each host connected to an SR by writing to the SR's
other-config:perfmon key.

CI-44: expire sessions based on username/originator specific quota

Based on some previous patches by Thomas Sanders.

The current algorithm is implemented as follows:

  * For sessions with their own auth_user_name (other than "root"/""), they will use their independent session quota (Xapi_globs.max_sessions_per_user_name) grouped by their auth_user_name. This can happen in following cases:
    - The session creator uses an external authentication method where the username is not the default
    - The session creator is logged in as local super user (hence no username/password authentication required) but still chooses to pass an independent username argument in purpose (e.g. vmpr, sm)

  * Sessions without independent auth_user_name (e.g. without RBAC, most external API users will have to share the same super user login) can still distiguish themselves using the new "originator" param during session creation. For sessions created with the optional "originator" argument, they will use their independent session quota (Xapi_globs.max_sessions_per_originator) grouped by their originator key.

  * All the rest sessions are in the common session pool, as before, sharing the default session quota (Xapi_globs.max_sessions). Among them, internal sessions will have higher prioirty than the external ones.
