license file rendered in binary format

[Peter Jose De Sousa]

Hello,

When using the most recent version of the landscape server charm the license file is rendered as binary. This causes landscape server to enter a crash loop:

[Steps to reproduce]

1. Deploy landscape. Landscape server charm revision 111
2. Set license file as base64
3. SSH to landscape instance and cat the license file: /etc/landscape/license.txt

The output will be binary.

[Workaround]

Downgrade charm to rev 102

Thanks,
Peter
