Need to delete Rabbit MQ queues for environments

[Timur Nurlygayanov]

Need to delete the Rabbit MQ queues for Murano environment when user deletes this environment.

We can see that after 4+ month of testing RabbitMQ server hangs with error ' ** WARNING ** Mnesia is overloaded:'

How it is works now:
1. User creates and deploys Environment
2. Murano creates the RabbitMQ queues for each VM in this Environment
3. User deletes Environment, all queues are still present

Now it is should work in the ideal system:
1. User creates and deploys Environment
2. Murano creates the RabbitMQ queues for each VM in this Environment
3. User deletes Environment, Murano deletes all queues for all VMs in this Environment

Need to verify the fix of this issue.

<sergmelikyan> nope
<tnurlygayanov> sergmelikyan, I remember that you make commit with fix for https://bugs.launchpad.net/murano/+bug/1250788 ?
<stanlagun> I thought we already solved it
<sergmelikyan> stanlagun, me too, but maybe something was lost during code migration between branches.
<stanlagun> with queue ttls
<tnurlygayanov> yes, need to verify it. what the ttl for queues now?
