…bsent (#1103)

make apt a soft dependency per styleguide (resolves #1086)

Ensure absent on concat resource for server resource with ensure => absent (#1103)

bump concat to <5.0.0 instead of <4.0.0 (#1107)

Without this change, the nginx https repository url is added to sources.list.d
and apt-get update is executed immediately after, failing because
apt-transport-https is not yet installed. Subsequently all package
installs fail because the apt cache has been invalidated.

With this change we ensure the apt-transport-https package is present
before running apt-get update. Since all sources are now https, the
package is always necessary, which is why I moved it out of the 'case'
statement.

Fix dependency on apt-transport-https
