BrAPI: set default germplasm acquisitionDate and use in filtering

[dwaring87]

Description

This adds more support for the acquisitionDate germplasm property in BrAPI endpoints:

• The germplasm acquisitionDate property will use the acquisition date stock property if it was manually added for a particular accession. When this is NOT present, it will use the stock create_date field (automatically set when a stock is added to the database) for the acquisitionDate. This ensures that every stock will have an acquisitionDate set (either the create_date by default or the acquisition date stock property, if set).
• Add additional filter parameters to the GET /germplasm and POST /search/germplasm BrAPI endpoints:
  • acquisitionDate - filter germplasm for an exact acquisition date
  • minAcquisitionDate - filter germplasm that have an acquisition date >= the param value
  • maxAcquisitionDate - filter germplasm that have an acquisition date <= the param value

Fixes #5303

it's not clear how the search works with acquisition_date, as it is just a match and not a smaller or larger than comparison

@lukasmueller acquisitionDate is an exact match, minAcquisitionDate is a >= match and maxAcquisitionDate is a <= match.
