Feature to define a pipeline timeout in Cloud Manager

[#1]

Request for Feature Enhancement (RFE) Summary:	Add timeout configuration to the pipeline
Use-case:	Pipelines can take a long time to finish, and the only way to cancel them is to contact Adobe support. While this is perfectly valid in cases when something is not working properly in the pipeline itself, it would be good to have the possibility to cancel pipelines in case there is something wrong with the user code, and there is no need for Adobe intervention.
Current/Experienced Behavior:	Pipelines can take up to several hours to fail.
Improved/Expected Behavior:	The configuration for the pipeline timeout is explicitly defined value in minutes, or as a relative threshold compared to the average calculated time over 90 days (this value is already shown in the pipeline).
Environment Details (AEM version/service pack, any other specifics if applicable):	AEM as a Cloud Service
Customer-name/Organization name:	Any
