    Remove spaces from SSH public key comment

    An SSH key generated by Nova contains the comment 'Generated by Nova'. Older
    versions (prior to 0.7.2) of cloud-init trip over the spaces in the comment
    and as a result of that the key injected into the root account is not disabled
    by cloud-init. Yes, it's a cloud-init bug but it's also a regression in the
    sense that older OpenStack installations (Essex and older) don't contain
    spaces in Nova generated key comments and thus older cloud-init's are not
    affected in these environments.

    This patch replaces the spaces with dashes, i.e., 'Generated-by-Nova'.

    Spaces were introduced by commit: 114109dbf4094ae6b6333d41c84bebf6f85c4e48
