add option --urls print package URLs instead of downloading

[oliverkurth]

The functionality is similar to --downloadonly, but just prints the URLs. This can be used for scripts that download the packages in another way.

Example:

$ sudo ./bin/tdnf --urls install --alldeps -q lsof | tee test.out

It's a good idea to use the -q option along with it, to suppress eventual "Refreshing metadata" messages.

Good addition, thank you.
Just one query, should we print "repo-name: " might help in some automations.

Also here, I want this very simple, so it can be easily used in scripts. However, maybe we can have an enhancement to it, maybe use the --info option for more information.

Understood, just use ARRAY_SIZE macro, LGTM. Approved.
