Improve man pages structure

There are too many options in ipa-*-install scripts which makes it
difficult to read. This patch adds subsections to install script
online help and man pages to improve readability. No option has
been changed.

To further improve man pages:

1) All man pages were changed to have the same header and top-center
   title to provide united look.

2) Few typos in man pages have been fixed

 An authorized user is required to join a client machine to IPA. This can take the form of a kerberos principal or a one\-time password associated with the machine.
 
 This same tool is used to unconfigure IPA and attemps to return the machine to its previous state. Part of this process is to unenroll the host from the IPA server. Unenrollment consists of disabling the prinicipal key on the IPA server so that it may be re\-enrolled. The machine principal in /etc/krb5.keytab (host/<fqdn>@REALM) is used to authenticate to the IPA server to unenroll itself. If this principal does not exist then unenrollment will fail and an administrator will need to disable the host principal (ipa host\-disable <fqdn>).
