Filter by RDS tag

Question

Hi,  
  I'm working on a script the requires me to filter by a certain tag within RDS.  If I run

```
for instance in source_instances:
    db_instances = "{0}".format(instance['DBInstanceIdentifier'])
    response = source.list_tags_for_resource(
             ResourceName=instance['DBInstanceArn'])
    print (db_instances)
    print (response)
```

I'm able to see the tags of each of my RDS instances, including the Environment tag.  
  
If I run

```
    for instance in source_instances:
        db_instances = "{0}".format(instance['DBInstanceIdentifier'])
        response = source.list_tags_for_resource(
            ResourceName=instance['DBInstanceArn'],
            Filters=[{
                'Name': 'Environment',
                'Values': [
                  'Production', 'production',
               ]
             }])
```

I get the following error  
ClientError: An error occurred (InvalidParameterValue) when calling the ListTagsForResource operation: Unrecognized filter name: Environment  
Any pointers would be appreciated.

Thanks for the help and sanity check.  After a little more digging, other post mentioned getting the ARN of the snapshot and use list_tags_for_resource to find the Taglist.  From there, it could be filtered.  
  
There's probably a little bit of a better way to verify the tag but this does work.  Source is the client connection to RDS.

```
#Gets the tags of the snapshot based on the snapshot ARN
        tagresponse = source.list_tags_for_resource(ResourceName=source_snap_arn)
        print ("Response", tagresponse)
        taglist = tagresponse['TagList']
        
        #Looks for the Value Production
        for tag in taglist:
            print (tag['Key'], tag['Value'])
            if tag['Value'] == 'Production':
                print ("Found Production Snapshot")
```

hi. after trying this for myself. I got the same result. Went to docs and found this.  Appears the SDK has the 'bones' (errors if providing the wrong Key Names (Name,Values), but not fully implemented.  
http://boto3.readthedocs.io/en/latest/reference/services/rds.html#RDS.Client.describe_db_instances  
(dict) --  
This type is not currently supported.  
Name (string) -- \[REQUIRED]  
This parameter is not currently supported.  
Values (list) -- \[REQUIRED]  
This parameter is not currently supported.

```
response = client.list_tags_for_resource(
            ResourceName='arn:aws:rds:ap-south-1:XXXX:db:deletemedb',
            Filters=[{'Name' : 'Environment', 'Values' : ['Production']}])

print(response)

botocore.exceptions.ClientError: An error occurred (InvalidParameterValue) when calling the ListTagsForResource operation: Unrecognized filter name: Environment

```
