Override Promyze URL for On-Premise versions

On-Premise version: 4.5.4

This is now possible to update through the Administration panel the URL of your Promyze instance (for On-Premise versions only). 

Go to Administration -> Configuration -> Override the THEMIS_URL environment variable. 

You should set the URL from which Promyze is available.

This value is enclosed in users' API keys for our plugins. In some cases, this environment variable is misconfigured and prevents the correct usage of plugins.
