Add export import variable for v2

[medamineziraoui]

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:

For scope GLOBAL edition:

For scope PROJECT creation:

For scope PROJECT edition:

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=[]}

to

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

• Write unit test for Export v2 and Import v2
