SSM: Require more fields

[ysangkok]

These were tested by trying the commands put-parameter, get-parameter
and get-parameters with awscli.

 % aws ssm put-parameter --name test-dec-20 --value "abc" --type String
{
    "Version": 1
}
 % aws ssm get-parameter --name test-dec-20                            
{
    "Parameter": {
        "Version": 1,
        "Value": "abc",
        "Type": "String",
        "Name": "test-dec-20"
    }
}
 % aws ssm get-parameters --names test-dec-20
{
    "Parameters": [
        {
            "Name": "test-dec-20",
            "Value": "abc",
            "Type": "String",
            "Version": 1
        }
    ],
    "InvalidParameters": []
}
 % aws ssm get-parameters --names test-dec-21
{
    "InvalidParameters": [
        "test-dec-21"
    ],
    "Parameters": []
}
 % aws ssm delete-parameter --name test-dec-20 
 % aws ssm delete-parameter --name test-dec-20

An error occurred (ParameterNotFound) when calling the DeleteParameter operation:

Fixes #740.

I am unsure of the naming, and I don't know how to verify it since I can't get Bazel working. Is it GetParameterResult or GetParameterResponse? configs/annexes/ssm.json uses Result but the source code uses Response. Same goes for the other names.

You'll want to use the names of the shapes in botocore when writing out typeOverrides. The generator normalises a bunch of different conventions from different services when generating the names of Haskell types.

Could you please also add a changelog entry?

[ysangkok]

Ok, added!

Thanks!
