When running "glance -v image-list" there's no store info listed, so
user cannot know the type of the backend. This patch added an new option
"--include-stores" and is to add the store id to the output of "glance
image-list --include-stores".

The final output may like:
+-----+------+-------------+-----+----------+--------+-----+------+
| ID  | Name | Disk_format | ... | Size     | Status |Owner|Stores|
+-----+------+-------------+-----+----------+--------+-----+------+
| xxx | img1 | raw         | ... | 10737418 | active | xxx | ceph |
| xxx | img2 | raw         | ... | 5086345  | active | xxx | file |
+-----+------+-------------+-----+----------+--------+-----+------+

When the Glance "multihash" is available on an image, the
glanceclient should use it instead of MD5 to validate data
downloads.  For cases in which the multihash specifies an
algorithm not available to the client, an option is added
to the image-download command that will allow fallback to
the legacy MD5 checksum verification.

Add checks to image-import command so that it provides better user
feedback in failure situations.

Change-Id: I8b6b32c3d1d1a745aa68ff8dc629419dff9bb130
Closes-bug: #1758718

Add checks to the image-create-via-import commmand so that it provides
better user feedback and doesn't begin the import workflow unless the
input has a chance of succeeding.  Preserves backward compatibility
with the current image-create command by (1) allowing an image record
only to be created when no import-method is specified AND no data is
supplied, and (2) doing the glance-direct workflow when no import-
method is specified AND data is provided.  Also adds the ability for
the import-method to be set as an env var OS_IMAGE_IMPORT_METHOD.
