[Feature] Job

[Slickbird]

Feature of #134

Description

Workflows contain collections of Scenarios to execute. Scenarios are executed atomically in database transactions (rolled back if execution fails) and culminate in an optional broadcast. This means that a single Workflow could contain multiple broadcasts (which can be useful for orchestrating staking-related transactions that affect a single account).

To perform a Workflow, we create a Job. This Job has a unique identifier and stores state for all Scenarios in the Workflow. State is shared across an entire Job so Actions in a Scenario can access the output of Actions in other Scenarios. The syntax for accessing this shared state can be found here.
