Delete commands for fuel config cli don't work if resource name is used

[Tatyana Kuterina]

Detailed bug description:
Delete commands for fuel config cli 'fuel2 config del' and 'fuel2 config rm override' don't work if resource name is used instead resource id. No error messages present but value is still in the list.

Steps to reproduce:
1. set config with key a and value 1
2. delete config with key a
3. set config with key b and value 2
4. override config with key b to value 3
5 delete override config with key b

Expected results:
2. config with key a is removed from the list
5. override config with key b is removed, value is 2

Actual result:
2. config with key a is still in the list
5. for key b - value is still 3

# fuel2 config get --env 3 --resource re_1

+-------+-------+
| Field | Value |
+-------+-------+
| a | 1 |
| b | 3 |
+-------+-------+

[root@nailgun tuning-box]# fuel2 config del -e 3 -r re_1 -k a
ResourceValue for key a was deleted

[root@nailgun tuning-box]# fuel2 config get --env 3 --resource re_1
+-------+-------+
| Field | Value |
+-------+-------+
| a | 1 |
| b | 3 |
+-------+-------+

Workaround:
Use resource id instead of resource name

    Additional redirects on resource name removed

    We don't need to redirect client if name is passed instead
    of the resource id. After redirect we will fetch exactly the
    same object. So with redirects we had only overhead with API
    requests handling and loading objects from the DB.
