epic(filter): filter by created_at and updated_at

[MR2011]

Each entity has the two timestamps:

• updated_at
• created_at

Allow filtering by these timestamps via API. The filtering should allow to filter for a range by using a start and end date.

  enum DateField {
    createdAt
    updatedAt
    deletedAT
  }

  input DateFilter {
    field: DateField!
    startDate: String
    endDate: String
  }

Example Steps for Service:

1. Add both filters to the ServiceFilter in internal/entity/service.go
2. Update database layer (internal/database/mariadb/service.go)
   2.1 update ensureServiceFilter()
   2.2 update getServiceFilterString()
   2.3 update buildServiceFilterParameters()
   2.4 add tests for GetServices() with the new filter options
3. Update api layer:
   3.1 Update ServiceFilterInput in api/graphql/graph/schema/service.graphqls
   3.2 Generate new implementation with gqlgen
   3.3 Set filter in ServiceBaseResolver in internal/api/graphql/graph/baseResolver/service.go
