Support for execution tasks

[mulahasanovic]

Issue

#882
#884

Intent - Support for execution tasks

• Add runAsTask config attribute.
• Insert the _executionTasks= url param (alongside _context=, _program= and _debug)
• Ensure that input tables are passed as blobs rather than text
• Insert a dummy blob when no inputs are provided (SAS Track CS0409737)

Implementation

• Improve tests coverage, test performance and add more execution task tests
• add new runAsTask config
• ensure input tables are passed as blobs
• insert dummy blob when file input is missing (with execution tasks enabled)

• All sasjs-cli unit tests are passing (npm test).
• (CI Runs this) All sasjs-tests are passing. If you want to run it manually (instructions available here).
• Data Controller builds and is functional on both SAS 9 and Viya
