Special characters in file share name is not supported by backend

[Shruthi-1MN]

Is this a BUG REPORT or FEATURE REQUEST?:
Special characters in file share name is not supported in backend but db entry is creating and getting 202 for creating request

Uncomment only one, leave it on its own line:

/kind bug
/kind feature

What happened:
Integration test case ran

It("TC_FS_IT_04: Create file share name having special characters ", func() {
			var jsonStr2 = map[string]interface{}{"name": "#FileShare Code!$!test", "description": "This is just for testxxx", "size": 2, "profileId": "df40af1a-17b5-48e5-899f-fa098b0bd5da"}
			url := "http://127.0.0.1:50040/v1beta/e93b4c0934da416eb9c8d120c5d04d96/file/shares"
			methodName := "POST"
			resp, _ := utils.ConnectToHTTP(methodName, url, jsonStr2)
			Expect(resp.StatusCode).Should(Equal(202))
		})

output is creating db entry

But backend is not supporting - osdsdock.log

What you expected to happen:
