How to set up and validate locally

1. Set up the ability to run workflow executions locally as described in PR 507
2. Run a workflow execution
3. Once completed, export it with:

   user = USER YOU MADE WORKFLOW EXECUTION WITH
   params_1 = {'export_type' => 'analysis', 'export_parameters' => {'ids' => [WORKFLOW_EXECUTION_ID]}, 'email_notification' => true, 'name' => 'test export'}
   DataExports::CreateService.new(user, params_1).execute

4. After 30s, download the export with:

   data_export = user.data_exports.last
   Rails.application.routes.url_helpers.rails_blob_url(data_export.file)

5. Copy and paste the above output into a browser. This should download the zip. The file directory should look like:

   |---- manifest.json
   |---- summary.txt.gz
   |---- Sample1.puid
   |           |---------Any attachments
   |
   |---- Sample2.puid
   |           |--------- Any attachments
   |---- etc.

   The manifest should look like:

   
   "type": "Analysis Export",
   "date": "Date.current",
   "children": [
   {
    "name": "summary.txt.gz",
     "type": "file"
   },
   {
     "name": sample1.puid,
     "type": "folder",
     "irida-next-type": "sample",
     "irida-next-name": sample1.name,
     "children": [
       {
         "name": "attachments.name",
         "type": "file",
       },
     },
   {
     "name": sample2.puid,
     "type": "folder",
     "irida-next-type": "sample",
     "irida-next-name": sample2.name,
     "children": [
       {
         "name": "attachments.name",
         "type": "file",
       },
     }
   ]

etc.
