Kiril Vladimirov	c30fc51b03	fix(datasource/CloudSigma): Make sure public ssh key is not empty Even when public ssh key is not set by the user, CloudSigma's server context has a key `meta.ssh_public_key` which is just an empty string. So instead of just relying on the "comma ok" idiom I make sure the value is not an empty string.	2015-02-21 19:31:01 +02:00
