default quotas too low for undercloud

[Robert Collins]

The default quotas cap out at 10 instances, but an undercloud is going to have many more instances, with a single or small number of tenants. We should have bootstack set them up much higher. E.g. 10000.

quotas are apparently defaulted in nova.conf; or we can make a tenant and set on the tenant. Tenant is probably better long term.

We probably need to set
# number of instances allowed per project (integer value)
#quota_instances=10

# number of instance cores allowed per project (integer value)
#quota_cores=20

# megabytes of instance ram allowed per project (integer
# value)
#quota_ram=51200

# number of floating ips allowed per project (integer value)
#quota_floating_ips=10

[Robert Collins (lifeless)]

e.g. for a 40 unit rack with 24 cores, 96GB of ram;
# number of instances allowed per project (integer value)
quota_instances=40

# number of instance cores allowed per project (integer value)
quota_cores=960

# megabytes of instance ram allowed per project (integer
# value)
quota_ram=3932160

# number of floating ips allowed per project (integer value)
quota_floating_ips=40

I'll take a look at this,

I'm guessing a script similar to init-keystone will be enough, how about setting to -1 by default?

nova quota-update --ram -1 <tenantid>
nova quota-update --cores -1 <tenantid>
nova quota-update --instances -1 <tenantid>
