Subject: Ask for admin password in ipa-adtrust-install

The credentials of the admin user will be used to obtain Kerberos ticket before
configuring  cross-realm  trusts  support and afterwards, to ensure that the
ticket contains MS-PAC information required to actually add a trust with Active
Directory domain via 'ipa trust-add --type=ad' command.
