feat(batch): support QuotaSharePolicy in scheduling policies

[matoom-nomu]

Issue

None

Reason for this change

cfn added QuotaSharePolicy to AWS::Batch::SchedulingPolicy

Description of changes

Add QuotaShareSchedulingPolicy to support the QuotaSharePolicy property on AWS::Batch::SchedulingPolicy.

CloudFormation treats FairsharePolicy and QuotaSharePolicy as mutually exclusive (Doc),
so this is implemented as a separate class from FairshareSchedulingPolicy, following the same pattern.

Describe any new or updated permissions being added

None

Description of how you validated changes

Added unit/integ test.
