MDTranslator ISO19115-2 to DCATUS: accrualPeriodicity

[FuhuXia]

User Story

In order to transform ISO19115-2 documents into DCATUS using mdtranslator, datagov wants to add processing for accrualPeriodicity

Acceptance Criteria

• GIVEN the DCATUS accrualPeriodicity field
  AND how the DCATUS writer expects to find the data within the internal metadata object
  WHEN the associated ISO19115-2 reader ruby modules are created
  THEN accrualPeriodicity should be transformed from ISO19115-2 to DCATUS

Background

• related to #4862
• We process 291017 ISO19115-2 datasets. We want all our datasets to be in DCATUS.
• This reader is not intended to be feature complete according to the ISO19115-2 standard. All we're looking to read is as much as the DCATUS writer expects.
• ISO19115-3 development workflow

Security Considerations (required)
