Aws-toolkit-jetbrains: Compatibility with localstack

[maranqz]

Is your feature request related to a problem? Please describe.
If we use localstack for correct using AWS Explorer should change default endpoint.

Describe the solution you'd like
Adding options to set endpoints for localstack aws services.

How would you envision this working? Effectively this would be a new "region" to the toolkit; would it make sense to have some sort of capability to add a region? Would need to be able to understand the differences between global (e.g. IAM) and regionalized services etc.

[maranqz]

Did I right understand that you say about this.

I thought it would be a new profile field endpoint_url.

There is plugin for aws-cli which prepares command calling for selected profile.
Also there is wrapper which adds endpoint-url in command.

[abrooksv]

The toolkit does not use the AWS CLI to make calls to AWS so the value of endpoint_url has no effect on the toolkit.

Allowing for a user to create a custom region may make sense as a feature though.

We currently will always make a call to sts::getCallerIdentity to validate the credentials are valid. We would need to figure out how to handle that in the world of custom of region.

[delitescere]

If it has to be hardcoded, I'd not suggest a new region, rather a new "partition", called localstack - but it'll still need to be configurable if the user has changed the port it's running on. (see https://github.com/aws/aws-sdk-java/blob/1.11.30/aws-java-sdk-core/src/main/resources/com/amazonaws/partitions/endpoints.json)

However, it would be far better if there was a configuration item in the IDE plugin that allowed the endpoint to be set (e.g. to http://localhost:4566).

The plugin would need to call the AWS SDK client setEndpoint, or the newer client builder withEndpointConfiguration.
