Use virtual names for known remote services in X-Ray

[rmccue]

For remote services we know, we should set them to fixed or formulaic names so that we can programmatically pull out statistics based on the edge (e.g. edge("altis-production", "elasticsearch.altis-production")).

Our database names follow a formulaic name of db.{stack}.{private_zone} so similar for ES/etc may be good. (We can't do this in TAS as it uses SSL.)

We definitely want to do this for the following:

• S3
• Elasticsearch
• CloudWatch Logs

We should probably also rename object-cache to match the same.
