Password generation and logging in ipa-server-install
When a randomly generated password contains a space character
as the first or the last character, installation fails on
kdb5_ldap_util calling, which does not accept that. This patch
fixes the generator to generate space only on allowed position.
This patch also ensures that no password is printed to
server install log.
