Offer variables for current Retry Count and maximum Retry Count

Current Situation

• Users would like to check from a job if execution is repeated due to a Retry Instruction. This includes to make available
  • the current retry counter,
  • the maximum number of retries.

Desired Behavior

• The following variables should be provided:
  • js7RetryCount: indicates the number of the current retry of a job within a Retry Instruction.
  • js7MaxRetryCount: indicates the maximum number of retries specified with the Retry Instruction.
• If the current job is not in scope of a Retry Instruction, then the js7RetryCount and js7MaxRetryCount variables hold empty values.

Delimitation

• Variables related to a Retry Instruction are not related to the existing js7JobExecutionCount variable that counts the number of executions of a job for a given Order ID independently from the fact that a job is repeatedly executed due to user intervention (for example suspend/resume operations) of by automated behavior (Retry Instruction).
