`service.storage_passwords.list` misses space in `username` field

[ghost]

Describe the bug service.storage_passwords.list misses space in username field.

To Reproduce Steps to reproduce the behavior:

1. Install https://splunkbase.splunk.com/app/2731/
2. Add

   [ test]
   account_name = ucspe
   account_password = ucspe
   disable_ssl_verification = True
   server_url = 10.141.36.107

   to local/splunk_ta_cisco_ucs_servers.conf.

3. Go to Splunk, open Cisco UCS app and refresh the page.
4. Run this Python script

   
   from splunklib.client import connect

service = connect(username="admin", password="")

all_passwords = service.storage_passwords.list(count=-1, search="")

for p in all_passwords: print(p.state)

5. See that username field does not have space, but the stanza that we add in step 2 has.

**Expected behavior**
Username field should have space in it.
