Description of problem:

When installing freeipa-client in a container, I've noticed wget gets
installed. Checking source code shows that it's only used in a couple of
trivial cases that could be converted to curl.

curl, unlike wget, is part of Core group:

# dnf group info 'Core' | grep wget
# dnf group info 'Core' | grep curl
   curl
#

Using it will make the footprint a little bit smaller.

Version-Release number of selected component (if applicable):

freeipa-client-4.2.3-1.fc23

How reproducible:

Deterministic.

Steps to Reproduce:
1. dnf install -y freeipa-client

Actual results:

Installing:
[...]
 wget                      x86_64   1.16.3-2.fc23               fedora    579 k

Expected results:

wget not installed.
