Task concatenation

Original by @VictorGrycuk

would it be possible to add an option to chain the tasks? If the first tasks finishes OK, the second one will be executed, and if that one finishes OK, the second one will be executed.

Both of these requests would make it similar to Microsoft Pipelines, in that you have a series of steps where the next depends on the previous, and all share variables.

## Use Case
There are times that I need to test bot libraries and bot samples, so I need to do the following:

Install dependencies
Build the library
Run the library tests
Package the library
Use the created package to build a bot sample
Run the bot sample tests
Deploy or Start the bot sample
I have created several scripts that do some combination of the above steps, but it would be awesome if I can move the above steps to gaucho, check a checkbox to select which steps I want to run sequentially, and run them.
