…cipationConditions

* Clarify VII.1 mapping.
* Use "nearest earlier date" construction.
* Rename durationRationale to periodRationale.
* Link to "Get a translation" operation.

…s to ignore.csv.

…oves fields.

Field name changes:

* Fix `type` to `documentType`
* Rename `minimumLevel` to `minimum`, to be more flexible for future criteria, which might set minimum values, percentages, ratios, etc.
* Rename `participationConditions` to `otherRequirements`
  * As mentioned by Giampaollo Sellitto in eForms/eForms#296 (comment), "participation criteria" or "participation conditions" are easy to confuse with "selection criteria" from a legal perspective. This is the reason ESPD uses "other criteria" and eForms uses "other requirements".
* Rename `reservedTo` to `reservedParticipation`, mirroring `hasReservedExecution`
* Rename `termsPerformance` to `performanceTerms`, to put words in regular order
* Rename `hasPerformingStaffQualification` to `requiresStaffNamesQualifications`, for clarity
* Rename `objectiveRulesCriteria` to `reductionCriteria`, see 2014/24/EU Article 65
* Rename `hasGuaranteeRequired` to `hasRequiredGuarantees`, to put words in regular order, and to allow multiple guarantees (like in some countries) open-contracting/standard#900

Modelling changes:

* Change `selectionCriteria` to an object, with a `criteria` array as a sub-field, like with `awardCriteria`
* Remove `isReservedToProfession` and rename `reservedToProfession` to `reservedExecution`, then use `hasReservedExecution` and `reservedExecution` for both sheltered employment programmes and professions
* Move `hasRequiredGuarantees` from `otherRequirements` to `submissionTerms`, see eForms
* Move `tendererLegalForm` from `otherRequirements` to `contractTerms`, see eForms

Code changes:

* Rename 'economicFinancial' to 'economic', to be consistent with the new `documentType.csv` code
* Rename 'economicCriteriaSelection' to 'economicSelectionCriteria', to put words in regular order
* Rename 'technicalCriteriaSelection' to 'technicalSelectionCriteria', to put words in regular order
* Rename 'publicServiceMission' to 'publicServiceMissionOrganization' and 'shelteredWorkshops' to 'shelteredWorkshop', so that codes describe a singular organization type

All forms:

* Copy mappings across forms
