Upload logs automatically after a command has been completed

[reubenmiller]

Is your feature request related to a problem? Please describe.

It is difficult and slow to debug an command (operation) which failed, as it is difficult for the user to retrieve the related log file to an command instance as there are generally many different log commands, and finding the correct log file to the latest operation is non-trivial.

Describe the solution you'd like

An option to enable the automatic uploading of a command's associated log file when a command finishes (e.g. the status is set to failed). The file should be uploaded to the cloud where the operation was created from.

It might make sense to have this setting configurable to support the following settings:

• upload on failure
• upload on successful and failure
• don't upload

Describe alternatives you've considered

Test Plan

The feature has been implemented as described, where the workflow log file of the operation is automatically uploaded on completion of the operations, if configured to do so. But the log upload is currently limited to software update operations only.

Auto log upload is disabled by default, which can be enabled by using the config setting : c8y.operations.auto_log_upload which supports values on-failure, always and never(default option).

E.g: tedge config set c8y.operations.auto_log_upload always

Three tests have been added to software.robot test to test the effect of all the config variants.
