cimi: fixed typo address_teplates -> address_templates
Tests: DTACLOUD-442 & DTACLOUD-441: ensure instances are running, stopped, resp. destroyed
This also prevents failures with fgcp where the ongoing creation
operation blocks subsequent creation/deletion operations until completed.
Related to DMTF cimi mantis 1974:

The state of a volume being created in fgcp is called "DEPLOYING", the
Deltacloud API documentation seems to leave it to the provider, with
examples of what ec2 returns. Ec2 (and cimi) define "CREATING". Aligning
what the fgcp driver returns with that. Same for snapshot "PENDING",
volume "NORMAL" and "BACKING_UP" states.
Cimi intended we use their state names for same states. Deltacloud has
"IN-USE" for volumes that are "AVAILABLE". Aligning this state with CIMI
for all providers. Whether a volume has been attached can be retrieved
through other attributes/apis.
Also, for fgcp, generate volume name if empty string specified (happens
with GUI), and align with cimi CREATING/AVAILABLE for snapshot states.

CIMI: Cleanup in CIMI base models

- CIMI::Model::Resource moved from base.rb to separate file
- The $select methods moved to a separate module
- CIMI::Model::Collection helpers now extend the Base class without
  reopening it (extend CollectionMethods)
- CIMI::Model::Base methods layout reorganized to be more readable

CIMI: Initial implementation of $filter parameter

This parameter should be able to filter all collections
using given key/value pair:

/cimi/machines?$filter=name="Mock1"

should return only those Machines with the 'name' attribute
set to 'Mock1'.

For now only '=' and '!=' operators are supported and only
one filter is supported in URL.
