Got none with improper name when querying resource provider list

[Eric Xie]

Description
===========
I created one resource provider with name that included some special symbols,
like '$', '@' at etc. Then i queried RP list with the name for filtering,
and it returned none.

Steps to reproduce
==================
* POST http://**IP**/placement/resource_classes
{
    "name": "RP_test-dks？#￥@！##"
}
* GET http://172.23.28.30/placement/resource_providers?name=RP_test-dks？#￥@！##
{
  "resource_providers": []
}

Expected result
===============
Validate 'name' when creating RP with strict rules.

Actual result
=============
Only check if string.
        "name": {
            "type": "string",
            "maxLength": 200
        },

Environment
===========
1. nova version

    Consider startup scenario in _get_compute_nodes_in_db

2. Which hypervisor did you use?
devstack + libvirt + kvm

At least as written, there appears to be no problem here: you're passing a URL without encoding the parameters. The unicode you've used in the name parameter needs to be encoded. Once done the URL will look like:

  /placement/resource_providers?name=RP_test-dks%EF%BC%9F%23%EF%BF%A5%40%EF%BC%81%23%23k

at which point the results will include the created resource provider.
