      Description

      1. Allow the user to define a timeout for a single operation execution. On expiration, the TOSCA container will mark the execution as failed with an indication that the cause was timeout.
      We can choose a default time unit for this value, we can decide of a pattern "20 m" or we can have another keyname "timeout_unit" that will describe it.
      IMHO, I think that seconds is the minimal time unit that will be required and it is a good default.

      2. Allow the user to define a retry for an operation execution.
      If an operation fails to execute (exit code != 0 or timeout), the TOSCA container will execute the operation again until reaching the number of retries.
