Adds a "simplified" floating IP management option.

Provides one-click associate and disassociated actions when in
"simple" floating IP management mode. Complex floating IP
management is still allowed via the access & security panel,
but in general it's not necessary except when managing multiple
floating IP pools or with complex network requirements.

Implements blueprint associate-ip-one-click.

Avoid cinder calls, when cinder is unavailable

When a volume service is not available, then a cinder client can not
be created. This patch skips the calls, so that dashboard doesn't
break any more.

Don't redirect when clicking instance detail page in admin panel.

Fixes bug 1096299.

Currently, when you click the instance detail information page
in admin panel, horzion will redirects to the project panel.
This is not reasonable. This patch fixes this problem by staying
on the admin panel when clicking the instance detail page.
