get-oui and get-iab cron job doesn't fetch updates

[nrauso]

With a cron job run every month, NethServer tries to fetch OUI and IAB updates.
This cron job is added by nethserver-diagtools package.

On many systems the updates fetch fails:

~]# /usr/sbin/get-oui -u http://standards-oui.ieee.org/oui/oui.txt
Could not get OUI data from http://standards-oui.ieee.org/oui/oui.txt
~]# /usr/sbin/get-iab -u http://standards-oui.ieee.org/iab/iab.txt
Could not get IAB data from http://standards-oui.ieee.org/iab/iab.txt

and it happens because now the URLs are redirected on https:

~]# curl -I -L http://standards-oui.ieee.org/oui/oui.txt
HTTP/1.1 302 Found
Date: Wed, 02 Mar 2022 11:02:59 GMT
Location: https://standards-oui.ieee.org/oui/oui.txt
Server: BigIP
Content-Length: 0
X-Cache: MISS from fw1.nethesis.it
X-Cache-Lookup: MISS from fw1.nethesis.it:3128
Via: 1.1 fw1.nethesis.it (squid/3.5.20)
Connection: keep-alive

On NethServer the necessary module to correctly manage the https URLs through perl scripts is missing.
To workaround the issue you need to install the missing module:

yum install perl-LWP-Protocol-https

After that, the updates fetch works flawlessly:

~]# /usr/sbin/get-oui -v -u http://standards-oui.ieee.org/oui/oui.txt
Renaming ieee-oui.txt to ieee-oui.txt.bak
Fetching OUI data from http://standards-oui.ieee.org/oui/oui.txt

Opening output file ieee-oui.txt
31552 OUI entries written to file ieee-oui.txt

~]# /usr/sbin/get-iab -v -u http://standards-oui.ieee.org/iab/iab.txt
Renaming ieee-iab.txt to ieee-iab.txt.bak
Fetching IAB data from http://standards-oui.ieee.org/iab/iab.txt
Fetched 2453481 bytes

4575 IAB entries written to file ieee-iab.txt

It could be a good idea to add perl-LWP-Protocol-https as a dependency of nethserver-diagtools.
