Unclosed socket in utils

[maxnoe]

Description

Follow up to #6787, a similar resource leak due to not using context managers for resource objects. In this case, a socket.

Steps to reproduce

The two sockets here:

❯ rg -F 'socket(socket.AF_INET'
lib/rucio/common/utils.py
1233:        s = socket.socket(socket.AF_INET6, socket.SOCK_DGRAM)
1241:            s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

are opened but never closed.
