Add export import variable for v2

Why ?

We would like to export new environment variables from v2 platform with the projectsExport. to then import to the same target environment with projectsImport task.

Actual status / Investigations

We checked for the api call for export v2: Those are the ones we need Query for getting all scope GLOBAL:

query globalEnvironmentVariablesQuery {
  globalEnvironmentVariables {    
    id    name    scope   value    description   isPassword  
  }
}

Query for getting all scope PROJECT:

query environmentVariablesQuery($projectId: UUID!) {
  projectEnvironmentVariables(projectId: $projectId) {
    id   scope   name    value   description   isPassword  
    overriddenValues {      
      id      scope     value     description     isPassword     
    }    
  }
}

Mutation for adding environment variables: For scope GLOBAL creation: image (8)

For scope GLOBAL edition:

image (9)

For scope PROJECT creation:

image (10)

For scope PROJECT edition:

image (11)

How?

Our work will be devided in two main part Export V2 and Import V2.

First part Export V2 :

[ ] Add object EnvVariable to groovy/io/saagie/plugin/dataops/models with properties EnvVariable Class
scope : String
include_all_var: boolean
name: ArrayList
[ ] Add getGlobalEnvironmentVariables to groovy/io/saagie/plugin/dataops/utils/SaagieUtils.groovy that will fetch all global variables
[ ] Add getProjectEnvironmentVariables to groovy/io/saagie/plugin/dataops/utils/SaagieUtils.groovy that will fetch all project variables
[ ] updating exportArtifacts to SaagieClient.groovy, add the logic to get the list of variables from one the the query getGlobalEnvironmentVariables or getProjectEnvironmentVariables depending on the value of scope (global|project)
[ ] Create a new Class ExportVariables that will include ExportVariables Class
name: string
description: string
isPassword: boolean
value: string
scope: string
overriddenValues: OverridenValues

OverridenValues Class

id: String
[ ] After mapping results from the environment variables query to ExportVariables we need to change the FolderGenerator and add method generateFolderForVariables that will create a new folder for the exported variables.

### Second part Import:

[ ] we need to added static method extractVariableConfigAndPackageFromExportedVariables in the groovy/io/saagie/plugin/dataops/clients/SaagieClientUtils.groovy whitch will extract the information for the exported variable.

[ ] We create a callback callbackVariablesToExport which will be responsible for creating or updating variables from mutations.
[ ] We create a new Class service ImportVariableService which will extract the Variable exported from the zip file and pass them to callbackVariablesToExport

[ ] we change the log for the the resulting success of the task projectsImport

{status=success, job=[{id=22712, name=jupyter/scipy-notebook}], pipeline=[]}

{status=success, job=[{id=22712, name=jupyter/scipy-notebook}], pipeline=[],env=[name=env1,name=env2}

[ ] Write unit test for Export v2 and Import v2
