Make type of Tags property consistent among services

[ivankeller]

Some resources like AWS::Glue::Job or AWS::Glue::Trigger expect a Json (Dict) as Tags Property while others like AWS::S3::Bucket or AWS::SQS::Queue expect a List. Use the more compact Dict syntax in all Tags Properties.

When using tags in several place on a YAML file it's useful to use anchor/alias. With two types of Tags it's necessary to define two series of tags, one for properties that expect Dict and one for properties that expect List.

Example of Dict and List syntax for the same 5 tags:

tagDict: &tagDict
  global.app: ${self:custom.service}
  global.env: dev
  global.opco: axa-be
  global.project: ${self:custom.project}
  global.DCS: datalab

tagList: &tagList
  - Key: global.app
    Value: ${self:custom.service}
  - Key: global.env
    Value: dev
  - Key: global.opco
    Value: axa-be
  - Key: global.project
    Value: ${self:custom.project}
  - Key: global.DCS
    Value: datalab
