[Feat]: Improve initial loading time for execution

[SarvJ1]

🔖 Feature description

Currently the plugin if serviceID is configured, makes 4 API calls for it to show the executions.This happens only during the first time you load the executions.

🎤 Context

• The first API is to check for the licenses issued to the account
• As we currently take latest 5 pipelines that have been executed for the particular service,for that we need the service name
• So second API gets us the service name which we will use to filter and get latest 5 pipelines
• Third API gets us the latest 5 pipelines with that particular service name
• Fourth API gets us our executions

Currently working on the new API which will help us to get executions for particular serviceID and pipelineIDs in one API call.
This should improve our initial loading time
