patch 8.1.0658: deleting signs and completion for :sign is insufficient
Problem: Deleting signs and completion for :sign is insufficient.
Solution: Add deleting signs in a specified or any group from the current
cursor location. Add group and priority to sign command
completion. Add tests for different sign unplace commands. Update
help text. Add tests for sign jump with group. Update help for
sign jump. (Yegappan Lakshmanan, closes #3731)
