pluggable typemapper

Description:

Added pluggable type mapper, that allows to provide configs in JSON files.

Example:

{
  "instrumentations": [
    {
      "entityType": "org.opengroup.osdu.core.common.model.legal.LegalTag",
      "fieldNameCustomMapping": {
        "countryOfOrigin": "COO",
        "createdDate": "created"
      },
      "fieldTypeCustomMapping": {
        "created": "shaded.osm.com.google.cloud.Timestamp",
        "expirationDate": "shaded.osm.com.google.cloud.Timestamp",
        "isValid": "java.lang.Boolean"
      },
      "identityTranslator": {
        "getIdMethod": "getId",
        "setIdMethod": "setId",
        "keyClass": "java.lang.Long"
      },
      "keyFields": ["id"]
    }
  ]
}
