Make gnt-node list-storage more standard
This patch adds support for the -o+field,… format that the other listcommands accept and changes the format of the allocatable field fromsimply str(bool) to Y/N.
Rename the node storage commands
To reduce confusion, the following gnt-node commands are renamed:

InstanceIpToNodePrimaryIpQuery: use a query dict
In 95b487b we changed InstanceIpToNodePrimaryIpQuery to be able to querymultiple instances at once. We also need to be able to query ipsbelonging to a specific nic link, so what we do is:
1) Move the "query" argument to a dict, containing different fields...
SimpleConfigReader: ips are partitioned by link
We were already half-doing it, but this completes the process.
1) We don't maintain a list of ips or an ip->instance map2) We add a new link,ip->instance map (link->ips list we had)3) We add the link parameter to GetInstanceByIp (making it...

Allow '@' in tag values

Try to reduce wrong errors in InstanceShutdown
In backend.InstanceShutdown(), there is a race condition betweenchecking that the instance exists and trying to shut it down whichtranslates sometime in error messages like:

Revert breakage introduced in e4e9b80
Commit e4e9b8064787df01a79846a40f49c8ae06a8eb0e introduced two problemsin backend.InstanceShutdown():
- first, it reduced the check interval significantly (especially for the first few checks); there are very few production VMs that shutdown in...
Xen: Ignore the retry argument in stop instance
Commit 4ad4511 changed the KVM hypervisor to send multiple shutdownrequests to the monitor, but it didn't change this for the Xenhypervisor. We simply remove the return on retry model, since we do wantto send multiple shutdown signals for both Xen and KVM (even if the...

mcpu: Implement lock timeouts
The timeout is always between ~0.1 and ~10.0 seconds. A smallvariation of ±5% is added to prevent different jobs fromfighting each other. After 10 attempts to acquire the locks witha timeout, a blocking acquire is made.
