Bug 1599189

Description of problem:

Openstack commands are failing in case the user's password contains a single '}' at any index within the password. 

Other command line clients like nova and neutron work fine.


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

python-openstackclient-3.2.1-3.el7ost.noarch

How reproducible:
100% both at the customer side and in the lab.

Steps to Reproduce:
1. Create a project and add a user. Make sure that the user's password contains a single curly brace.

[stack@undercloud ~]$ openstack project create --description 'testproject' testproj
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | testproject                      |
| enabled     | True                             |
| id          | e43536802a7e405098385a65427ca4d1 |
| name        | testproj                         |
+-------------+----------------------------------+

[stack@undercloud ~]$ openstack user create --project testproj --password redhat}123 testuser1
+------------+----------------------------------+
| Field      | Value                            |
+------------+----------------------------------+
| email      | None                             |
| enabled    | True                             |
| id         | 09a179ba3ee34b40b735bcc61596c0bd |
| name       | testuser1                        |
| project_id | e43536802a7e405098385a65427ca4d1 |
| username   | testuser1                        |
+------------+----------------------------------+

2. Create a rc file for the user:
[stack@undercloud ~]$ cat testprojectrc 
# Clear any old environment that may conflict.
for key in $( set | awk '{FS="="}  /^OS_/ {print $1}' ); do unset $key ; done
export OS_USERNAME=testuser1
export OS_TENANT_NAME=testproj
export NOVA_VERSION=1.1
export OS_PROJECT_NAME=testproj
export OS_PASSWORD=redhat}123
export OS_NO_CACHE=True
export COMPUTE_API_VERSION=1.1
export no_proxy=,192.168.122.47,192.0.2.6
export OS_CLOUDNAME=overcloud
export OS_AUTH_URL=http://192.168.122.47:5000/v2.0
export PYTHONWARNINGS="ignore:Certificate has no, ignore:A true SSLContext object is not available"

3. Try to run openstack commands:

[stack@undercloud ~]$ openstack server list
Single '}' encountered in format string

[stack@undercloud ~]$ openstack volume list
Single '}' encountered in format string

4. Other command line clients work fine:

[stack@undercloud ~]$ glance image-list
+----+------+
| ID | Name |
+----+------+
+----+------+


Actual results:
Openstack command line client does not work when the password contains a single brace

Expected results:
The commands run with the openstack command line client should work fine.
