Config setting to override image pull credentials type

[joschi]

The aws codebuild start-build command in the AWS CLI has a parameter --image-pull-credentials-type-override to override the service role used to pull/provision the custom images in a AWS CodeBuild build project.

Unfortunately the AWS CodeBuild Jenkins Plugin seems to be missing this configuration setting.

--image-pull-credentials-type-override (string)

The type of credentials AWS CodeBuild uses to pull images in your build. There are two valid values:

CODEBUILD
Specifies that AWS CodeBuild uses its own credentials. This requires that you modify your ECR repository policy to trust AWS > CodeBuild's service principal.

SERVICE_ROLE
Specifies that AWS CodeBuild uses your build project's service role.

When using a cross-account or private registry image, you must use SERVICE_ROLE credentials. When using an AWS CodeBuild curated image, you must use CODEBUILD credentials.

Possible values:

• CODEBUILD
• SERVICE_ROLE
