Remove excess data fetching on /training/common-intents page

[IgorKrupenja]

Note

This is a sub-issue of #700

Acceptance Criteria

• All AC of Remove excess data fetching in Training Module #700 apply
• The scope of this task is /training/common-intents and all of its sub-pages

[IgorKrupenja]

• Should use the common IntentDetails component implemented in Remove excess intent fetching on /training/intents page #731 to remove all duplicate code. The common component might need some tweaks.
• Remove unused common.yaml?
• Remove unused full.yaml and check related stuff. get_intents_with_examples will not be used too.
• rename examples_count to examplesCount when possible with changes in CommonIntents

Please test the following:

• During initial page load, the new intents/with-examples-count request returns only the minimal data needed to render the list, without examples, responses etc. Responses and rules are not requested at this point.
• After you click on an intent, the new intents/by-id, response-by-intent-id, rule-by-intent-id requests should return the data for that particular intent only.
• There are no obvious issues on the page, everything including examples and responses are rendered correctly.
• Suggest testing after [BUG] Entities requests broken on intents page #790 and [BUG] get_response_by_intent_id Unable to handle empty responses. Buerokratt-Chatbot#1115 fixes are deployed.
