Add ALL-IN operator to extra spec ops

Registered by Facundo Maldonado on 2014-06-05

This blueprint aims to allow querying if ALL of the given values are present in a list.
Currently there are is support for IN operator that returns True if a given element is present in a list. And, the OR operator that only work for single values.

 Example:

Suppose I want a flavor to be placed on a host that have the cpu flag 'aes' and 'vmx'.
Non of the existing operators can be used to describe this condition.
The <in> operator only works for just one element.
The <or> compares an element or each of the given elements against a single value.

I can't also repeat the <in> operator. As the extra specs is a dict, the flavor extra-spec key would be the same:

  capabilities:cpu_info:features : <in> aes
  capabilities:cpu_info:features : <in> vmx

  Just one of them will be saved.

  I need something like this:

  capabilities:cpu_info:features : <all-in> aes vmx

This blueprint propose the addition of this operator to the existing extra_specs_ops's operators set.
