slapos.cookbook provided it before, but it is simple functionality, which does
not need so many dependencies.

Such profile will download https://some.url/file and put it in

filename parameter can be used to change destination named filename.
destination parameter allows to put explicit destination.
md5sum parameter allows pass md5sum.
mode (octal, so for rw-r--r-- use 0644) allows to set mode
Exposes target attribute which is path to downloaded file.
