How reproducible:
Always

Steps to Reproduce:
1. When run virt-who in CLI mode with --hyperv-password=Welcome&*$001, it will show error info as the following:
[root@hp-z220-05 virt-who.d]# virt-who --hyperv --hyperv-owner=Default_Organization --hyperv-env=Library --hyperv-server=10.73.5.227 --hyperv-username=administrator --hyperv-password=Welcome&*$001 -o -d

-bash: *-bash01: command not found
[root@hp-z220-05 virt-who.d]# 2017-01-11 22:41:15,185 INFO: Using configuration "env/cmdline" ("hyperv" mode)
2017-01-11 22:41:15,186 INFO: Using reporter_id='hp-z220-05.qe.lab.eng.nay.redhat.com'
2017-01-11 22:41:15,248 ERROR: Virt backend 'env/cmdline' fails with error: Incorrect domain/username/password
2017-01-11 22:41:15,249 INFO: Waiting 60 seconds before retrying backend 'env/cmdline'

2. Click on "Ctrl + c" to end the session

3. Check virt-who's processes
[root@hp-z220-05 virt-who.d]# ps -ef|grep virt-who
root      7274  4751  1 22:37 pts/1    00:00:00 /usr/bin/python /usr/bin/virt-who --hyperv --hyperv-owner=Default_Organization --hyperv-env=Library --hyperv-server=10.73.5.227 --hyperv-username=administrator --hyperv-password=Welcome
root      7281  7274  0 22:37 pts/1    00:00:00 /usr/bin/python /usr/bin/virt-who --hyperv --hyperv-owner=Default_Organization --hyperv-env=Library --hyperv-server=10.73.5.227 --hyperv-username=administrator --hyperv-password=Welcome
root      7287  4751  0 22:38 pts/1    00:00:00 grep virt-who

4. If add quotes to --hyperv-password, it also failed to enter hyperv as "Incorrect domain/username/password"
[root@hp-z220-05 virt-who.d]# virt-who --hyperv --hyperv-owner=Default_Organization --hyperv-env=Library --hyperv-server=10.73.5.227 --hyperv-username=administrator --hyperv-password="Welcome&*$001" -o -d

Actual results:
1. As --hyperv-password with special characters as "&*$", it will failed to enter hyperv. Meanwhile, "ctrl+c" can't end debug mode.
2. Virt-who handle quotes to normal character

Expected results:
1. Although --hyperv-password with special characters as "&*$", it should enter hyperv successfully. Meanwhile, "ctrl+c" should end debug mode.
2. Virt-who should escape all characters in quotes:
for example: "Welcome&*$001" should escape to Welcome&*$001.

Additional info:
If configure password to non quotes (password=Welcome*&$001)or with quotes(password="Welcome*&$001"), virt-who can handle in to Welcome*&$001, virt-who can connect hyperv successfully.
