hard to remove file-or-link

1  files.file(path='/etc/resolv.conf', present=False)
2  files.link(path='/etc/resolv.conf', present=False)
3  files.template(src='templates/resolv.conf.j2', dest='/etc/resolv.conf', ns='10.2.0.1')

If I run 1,2,3 I get
--> pyinfra error: /etc/resolv.conf exists and is not a file

If I run just 2,3 I get (on another host)
--> pyinfra error: /etc/resolv.conf exists and is not a link

If I run just 3 I get no errors, but I'm left with some hosts having a symlink and some having a file.

I expected just 3 to work and replace symlinks with the templated file.

May be related to #791

Start by reproducing the three sequences in the issue with files.file, files.link, and files.template on hosts where /etc/resolv.conf is a file or symlink. Read the implementations of those operations and compare their handling of existing paths. Done means the templated file operation works consistently when /etc/resolv.conf is either a file or a symlink, with regression coverage for the reported cases.
