django-DefectDojo: Endpoint with protocol length > 20 characters causes error in report uploads (Tested with nessus)

When importing an endpoint which has protocol length > 20 characters the import fails

error in UI :

An exception error occurred during the report import:value too long for type character varying(20)

Causes of the problem is a restrictive max_length=20 in the Endpoint model :

class Endpoint(models.Model):
    protocol = models.CharField(null=True, blank=True, max_length=20,
                                 help_text="The communication protocol/scheme such as 'http', 'ftp', 'dns', etc.")

Example string causing error: as seen below the string is 21 chars

fw1-topology-download://xx-0-0-0-0.xx-xx-x.xxx.xxxx

By truncating the endpoint as the example below is possible to upload the Nessus report :

fw1://xx-0-0-0-0.xx-xx-x.xxx.xxxx
