List (server) details API ignores 'host' filter

[Unmesh Gurjar]

Branch: master

Scenario:
1. Use the 'nova list --host <host-name>' command to list instances on a specific Compute host.
2. Observe the result returned.

Actual Results:
The 'host' filter is ignored and all the 'active' instances are reported.

Expected Result:
Only the instances running on the specified host should be reported.

Observation:
1. The API specification for List details server ( v2/{tenant-id}/servers/detail ) does not list 'host' in the request parameters.

Solution:
1. Support should be added in Nova list server details API to consider the 'host' parameter.
2. The 'nova list' command help should be updated (remove the 'host' parameter from it).

For the 'nova list' command the flags '--host' , '--instance-name' , '--ip', '--ip6' are allowed for use by user which have "admin" role. So to fix this bug , we should

Update the "nova help list" output in python-novaclient such that these flags '--host' , '--instance-name' , '--ip', '--ip6' contain a help note "(Admin only)" in the end of their description.

I think this bug doesn't need to be fixed in nova, so I change it to 'invalid', if its incorrect, fix me pls.
