be useful for moving the API bindings out of XenModel.

- added a new precheck, called "Live patching status" which checks is a reboot is needed for each host. If reboot is needed, the check will display a warning, otherwise it will show a green tickbox, saying that the server does not need to be rebooted, and if live patching is used, this information will be included as well.

- Pool_patch.precheck can fail with the xapi error OUT_OF_SPACE when is trying to copy the patch from master to the slaves. This happens before the patch-precheck checks if enough space is available for installation. Therefore is different from the error we are currently processing, PATCH_PRECHECK_FAILED_OUT_OF_SPACE
- If the precheck fails with OUT_OF_SPACE then we try and retrieve the disk space requirements and report a HostOutOfSpaceProblem.
- Changed the PatchPrecheckCheck to try and find problem from a xapi failure, as well as from the result of the precheck call.
- Also removed ampersand from the the link labels (More Info and Clean up)

- Added three Warning classes (HAEnabledWarning, WLBEnabledWarning, HostNotLiveWarning), used in the Pre-checks page of the Install wizard (also in the Rolling Pool Upgrade wizard) to indicate that a check was skipped and the reason why.
- If HA or WLB is on, we show this as an error in the "HA and WLB status" check and the "VM migration status" checks will be skipped (with a warning displayed) for all the hosts in the pool.
- Similarly, if a host if unreachable, we show this as an error in the "Host liveness status" check and the following checks for that host will be skipped (and warning displayed).
