Block Device Timers in Nova (Missing Variables)

[Tim Way]

The variables:

block_device_allocate_retries
block_device_allocate_retries_interval

Are needed for use in nova.conf on compute hosts. These allow us to tweak how long Nova waits for storage by default the interval is 3 seconds and retries is 60. In most LVM based test setups launching more than 1 instance of anything but Cirros will fail due to these timeouts being exceeded.

Additionally, locally adding them manually to nova.conf is of course overwritten when the os-nova play is run again.

My setup: CentOS7 using stable/pike of openstack-ansible

You don't need that variable to override the nova.conf with our config_template mechanism.

Although i think it would be a nice addition for our operations guide.
