Step with ignore error = true and output calculation failure

[vhadianto]

Current thought is to not fail the step but add the output calculation failure to the step error.

[vhadianto]

We have a list of questions at this point.

When error ignore true is on, how do we handle these cases:

• step output render error
• throw if condition render error
• throw
• loop render error
• retry render error

Same question probably applies for when retry { } should be used ... does it apply to the things above?

There are three types of errors in a pipeline run:

• evaluation error, e.g. unknown attribute on referenced var
• unexpected error during a step, e.g. image not found
• runtime error, e.g. non-zero exit code

Evaluation errors always fail the step immediately and completely. The retry and error block settings are ignored.

Unexpected and runtime errors are handled by the user and their pipeline definition. They respect retry and error block settings for the step.

In the future we could add a new property to the error and retry blocks to optionally handle evaluation errors.
