Allow overriding EndpointUrl for AWS-related scalers

[barndawe]

Proposal

AWS Go SDK client allows for passing in an EndpointUrl parameter to override the AWS endpoint url (see Config struct for AWS client. Currently Keda does not allow for specifying this, e.g. for the SQS scaler, so it is not possible to run Keda against anything but full-fat AWS.

Use-Case

Adding the ability to override the EndpointUrl would allow Keda to be pointed at a Localstack SQS queue (https://docs.localstack.cloud/aws/sqs/).

Anything else?

Makes sense, are you willing to contribute this?

I can take a look if the issue reporter don't want to (I think we can give him few more days to respond)

@aviadlevy

did you start to do it? (or still want to do it?)
It was a few months and I think we don't have any response from reporter...
I can do it if no one going to do
