Use spread

[sed-i]

Issue

• The javascript actions operator is difficult to maintain.
• Vectorization of integration tests currently depends on the github ci language.

Solution

Use spread.

• task/suite or promtool check rules and promtool test rules (refs: 1, 2, 3)

Testing Instructions

$ spread

@cmatsuoka would you be able to take a look at this draft?

1. Wdyt about the file organization?
2. How can I check why it hangs? It is the same setup script I have in the multipass charm-dev blueprint.
