Add ECA action plugin to load environment name

Problem/Motivation

Hi,

I am using ECA for a bunch of automated functionality. I want an easy way to make sure this functionality only runs in production, particularly when it interacts with external services -- social media, payment gateways, email sending, etc.

The simplest approach I can think of is to simply create an action plugin to load the environment indicator name, for the current environment -- this can then be used with a condition to stop processing for particular environments.

Steps to reproduce

Proposed resolution

New Action plugin.

Remaining tasks

User interface changes

API changes

Data model changes
