Description of problem:
 PATCHing the 'name' with non-alphanumeric characters does not work for crush_rule api. It does not fail and does not change the name also. It should either fail or change the name. 

Version-Release number of selected component (if applicable):10.1.1-1.el7cp

How reproducible: always

Steps to Reproduce:
1. PATCH the crush_rule api for name with non-alphanumeric characters. e.g., replicated_ruleset_Test_#!@[ ?;
2. PATCH operation completes with:

{
    "request_id": "d4aa85ea-56d4-4758-90d7-13b3f128cd55"
}
3. Do GET on this crush rule.

Actual results:
The name is not changed
