`@kie-tools/form-generation-tool`: Improve the CLI to support other input sources to generate form

[pefernan]

Currently the form-generation-tool only allows as a input the json schemas generated in a kogito app, which means that, as a previous step we need a kogito app locally compiled.

It would be good if we could enable the tool to support different inputs, for example:

• A running Kogito App URL: Using the the openapi.json of a running app the cli could fetch the process and tasks schemas and generate the forms for them in the current folder (ot a target folder)
• A data-index URL: With the Data Index URL, the tool could query for the process definitions and service-urls and get it's schemas and trigger the form generation from there.

Additionally, the tool behaves as a dialog asking for input from the user, it would be good if we could pass all the needed info to the tool as arguments and it executes in silent mode.

Great enhancement suggestions @pefernan. +1 for a non-interactive mode and other sources of input.
