Blue Prism log should take in account duration of each execution stage

[DominiqueDALLER]

To be able to tackle performance issues, the Blue Prism log should take in account the duration of each stage.

Firstly, the Blue Prism log should display the duration of each stage in the log, not just the 'resource start' or 'resource end'. And as some stages are unseen given the log settings, the Blue Prism log should include at the end, the duration of all unseen stages, and the total duration of the process.

Secondly, Blue Prism should include a setting to display a stage in the log if its duration is greater than a defined value (in the system). For example, all stages with duration greater or equal than 30 seconds are displayed in the log, even if the setting in the studio is none or error only.
