Configurable API tool

[bluera-ai]

Overview
The api_caller community tool should be able to accept a preset configuration on __init__, so that an agent using it does not have to know about the contract of the API called when calling process, allowing for easier and reliable agent interactions, and lowering the precision requirement of the Universal Model powering the agent.

Requirements

• The API Caller community tool should be configurable on __init__ according to the above description.
• Tests must prove compatibility for all of all changes.
