membership template management

As an TYPO3 Association administrator, I want to manage the benefits of a membership in a structured way. Data will be provided as json or similar by typo3.org, will always be used for new memberships (new, renewal, up- or downgrade). (Note: extend tx_t3omembership_domain_model_membership)

UAC:

• Login to typo3.org BE
• use a BE module to access the templates
• after data change, trigger the export of data to the static json endpoint accessible by typo3.com middleware
