Read template's expected value orchest test Part-2

In tests under /tempest/api/orchestration/, resources gets
created based on parameters defined in template (yaml, json).
But while verification of output, expected values are hard coded
in tests.
Expected values should be read from template only.
This patch covers the following files -
    test_environment.py
    test_nova_keypair_resources.py
    test_swift_resources.py

Add "capabilities:" to multiple_backends extra-spec key

cinder-scheduler uses all the "capabilities:" to scope the
cinder-volume. With no "capabilities:" prefix set in extra_spec,
it will be no effect from cinder-scheduler to schedule the
cinder-volume, which is not the purpose of the testcase.
To address the review comment, This change will not remove but
adds 2 cases for the "capabilities:" prefix to volume type key:
extra-spec "capabilities:volume_backend_name".

Fixes incorrect assertion check

assertNotIn/assertIn does not work if the second
variable is of type List of dictionaries.
Suppose if it of only dictionary type, it will try
to match only 'key' but not 'value'.
Hence, the assertion check done here is not correct.

This patch fixes an incorrect assertion check for
"BasicOperationsImagesTest.test_delete_image" test
