Description of problem:

configchannel.createOrUpdatePath() strips the return line '\n' character from the end of the file. 


Version-Release number of selected component (if applicable):
Red Hat Satellite 5.7


How reproducible:
100%


Steps to Reproduce:

--- API script
↪ cat upload_configfile.py 
#!/usr/bin/python
import xmlrpclib
import os
import base64

SATELLITE_URL = "http://orbital.usersys.redhat.com/rpc/api"
SATELLITE_LOGIN = "admin"
SATELLITE_PASSWORD = "redhat"

client = xmlrpclib.Server(SATELLITE_URL, verbose=0)
token = client.auth.login(SATELLITE_LOGIN, SATELLITE_PASSWORD)

cf_channel = raw_input("Config Channel: ")
cfg_path = raw_input("Config File: ")

try:

    if os.path.isfile(cfg_path):
        with open(cfg_path, 'r') as fd:
            isDir = False
            #enc_cfg = base64.b64decode(fd.read())
            enc_cfg = fd.read()

    ct = {}
    ct['contents'] = enc_cfg
    #ct['contents_enc64'] = True
    ct['contents_enc64'] = False
    ct['owner'] = 'root'
    ct['group'] = 'root'
    ct['permissions'] = '644'
    ct['macro-start-delimiter'] = '{|'
    ct['macro-end-delimiter'] = '|}'
    ct['binary'] = False

    ret = client.configchannel.createOrUpdatePath(token, cf_channel, cfg_path, isDir, ct)

except:
    raise
client.auth.logout(token)

   So to test it, the file we want to has this content (with the return line)

# cat /etc/test-file-API 
this is a file
#


   Then uploading it via the and deploying to the client we got the issue reproduced:

↪ ./upload_configfile.py
Config Channel: test-configs
Config File: /etc/test-file-API

 --- on the client

[root@localhost ~]# rm -f /etc/test-file-API ; rhncfg-client get /etc/test-file-API ; cat /etc/test-file-API
Using server name orbital.usersys.redhat.com
Deploying /etc/test-file-API
this is a file[root@localhost ~]

  Note: if we edit the file via webUI and add manually the return line, the file is deployed as expected.


Actual results:

 \n is being stripped on Serializer when file is upload

Expected results:

 respect what the contents of the file
