Make the error log messages relatable to the bridge api concepts

[tmasternak]

Describe the suggested improvement

Overview

The bridge fails to move messages from one side to the other it logs error messages. This is a sample message:

Failed to shovel message for endpoint error with id from to
---> System.Exception: No target address mapping could be found for source address:

. Ensure names have correct casing as mappings are case-sensitive. Nearest configured match:

Potential improvements:

• Don't use the term "shovel" (unless someone used RabbitMQ in the past this is not a well-known concept).
• The error message mentions "address mapping" which does not relate to any of the existing API configuration options. This should relate e.g. to endpoint registration
• The error does not provide any advice on what could be a potential resolution of the problem e.g. consider adding HasEndpoint("<name>") call on the <side-b-name>

This should be changed for all the error messages logged by the bridge.
