Description

Add a new API method to get logs of the code processing:

• GetLogs

This method should get all existing logs of the code processing for the certain `pipelinedId` from the cache using `pipelineId` as a key and a new subKey `Logs`. This method also should save the index of the log which have been already sent to the client.
