Description of problem:

If there is a netowrk card which has upper case in its identifier, satellite always changes it to lower case in kickstart file making provisioning fail and bond not to come up


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

6.11

How reproducible:

100%

Steps to Reproduce:
1.have interfaces like enP2s2091f0,enP1s2088f0
2.configure netoworking in satellite
3.provision the server
4. check its kickstart file

Actual results:

bondslaves=enp1s2088f0,enp2s2091f0

later in ks file

# enP2s2091f0 interface

# enP1s2088f0 interface


Expected results:

bondslaves=enp1s2088f0,enp2s2091f0

later in ks file

# enP2s2091f0 interface

# enP1s2088f0 interface

Additional info:

responsible code is 

/usr/share/foreman/app/models/nic/with_attached_devices.rb


def attached_devices=(devices)
    devices = devices.split(SEPARATOR) if devices.is_a?(String)
    super(devices.map { |i| i.downcase.strip }.join(SEPARATOR))
  end

we should remove downcase from the code
