Inconsistency between os-quota-sets code and API doc

[Qiu Yu]

There's some inconsistencies I found between documentation and os-quota-sets / os-user-quotas api extension code.

#1. for the os-quota-sets extension, tenant_id should be explicitly passed as resource id so that admin could query quota for any tenant id.
#2. for the os-user-quotas extension, user_id should be passed as query string instead of resource id

So instead of following spec as documented, it should be

        GET v2/​{tenant_id}​/os-quota-sets
        Shows quotas for a tenant.

should be: GET v2/​{tenant_id}​/os-quota-sets/{tenant_id_to_query}

        PUTv2/​{tenant_id}​/os-quota-sets
        Updates quotas for a tenant.

should be: PUT v2/​{tenant_id}​/os-quota-sets/{tenant_id_to_update}

        GETv2/​{tenant_id}​/os-quota-sets/defaults
        Gets default quotas for a tenant.

should be: GET v2/​{tenant_id}​/os-quota-sets/{tenant_id_to_query}/defaults

        GETv2/{tenant_id}/os-quota-sets/{user_id}
        Shows quotas for a specified tenant and user.

should be: GET v2/​{tenant_id}​/os-quota-sets/{tenant_id_to_query}?user_id={user_id_to_query}

        POSTv2/{tenant_id}/os-quota-sets/{user_id}
        Updates quotas for a specified tenant and user.

should be: PUT v2/​{tenant_id}​/os-quota-sets/{tenant_id_to_update}?user_id={user_id_to_update}

        GETv2/{tenant_id}/os-quota-sets/detail
        Shows details for quotas for a specified tenant.

NOTE: This one is implemented in v3 api, and *NOT* mentioned by api doc
should be: GET v2/​{tenant_id}​/os-quota-sets/{tenant_id_to_query}/detail

        GETv2/{tenant_id}/os-quota-sets/{user_id}/detail
        Shows details for quotas for a specified tenant and user.

NOTE: This one is implemented in v3 api, and has already been documented. Not sure if it should be there though, since it's v3 only.
should be: GET v2/​{tenant_id}​/os-quota-sets/{tenant_id_to_query}/detail?user_id={user_id_to_query}
