Description of problem:
There is no option called as '-N' in ipa-server-install, but man page describes
this option in documentation

Version-Release number of selected component (if applicable):
ipa-server-4.2.0-3.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install ipa-server and dependent packages
2. Run
ipa-server-install -r EXAMPLE.COM -n example.com -p root1234 -a root12345
--hostname ipaserver.example.com -N


Actual results:
ipa-server-install: error: no such option: -N

Expected results:
Remove '-N' option from man page of ipa-server-install package and respective
documentations

Additional info:

I think the problem here is rather in the code. FreeIPA before 4.2.0:

# ipa-server-install -h | grep -i NTP
    -N, --no-ntp        do not configure ntp

FreeIPA 4.2.0:

# ipa-server-install --help | grep -i NTP
    --no-ntp            do not configure ntp

The short option is missing. Ticket is due.
