Description of problem:

Using hammer to dump templates out, it will not prompt
for the password when redirecting the output to a file,
resulting in an error.

Passing the --password option to hammer does work but
is not acceptable as this leaves the password in clear
text in the users history.

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

6.1.7

How reproducible:

100%

Steps to Reproduce:
1. # hammer --username admin template dump --name epel > snippet-epel.erb
2.
3.

Actual results:

# hammer --username admin template dump --name epel > snippet-epel.erb
Invalid username or password


Expected results:

As per when hammer is run without redirecting to a file

# hammer --username admin template dump --name epel
[Foreman] Password for admin: 


Additional info:

Customer has suggested that dump should have a switch to send
the output to a file, in the same way as the create has a switch 
to import from a file.
