now only two states are available enabled/disabled_
get weight for backend server, is default behavior for both state,
supports set weight while enable server in lb pool
misplaced the checkmode support (#L146) [FIXED]
no need to check if host is not set as the argument spec (#L138), it should already complain about that [FIXED]
Also moves the calculation of the destination file name until after
the slurp of the file contents, since the source as returned by slurp
may now be different, so we want to use that expanded path locally.
Fixes#8942
The content of the sha256sum attribute should be lowered before comparing it with the calculated sha256sum.
In the following example the used sha256sum uses ABC.. and not abc.. and the check failed. This should not happen.

* Adds another module utility file which generalizes the
access of urls via the urllib* libraries.
* Adds a new spec generator for common arguments.
* Makes the user-agent string configurable.
Fixes#6211
A fix for uri module regarding following redirects. The old behavior would follow redirects either way. This change clarifies the functionality and makes it a bit more explicit. Comparing the old behavior to the new 'yes' == 'all', 'no' == 'safe' and now 'no' will not follow any redirects. Historic behavior is still supported and documented with a push to the new values.
This is accomplished by not setting the If-Modified-Since header,
and setting "cache-control: no-cache" instead. Note that if the
file content has not changed, the module will still report that
changed=false, as the md5's of the tmp file and existing file are
compared before swapping
Fixes#5104
(fixes issue #4277)
* The sha256sum error message now displays the invalid
destination checksum if it doesn't match the one that
is specified in the arguments. This is useful for
debugging purposes.
* Non-alphanumeric characters, including the infamous
Unicode zero-width space, are removed from the sha256sum
argument prior to the check.
