Check if mysql allows login as root/nopassword before trying supplied credentials.
Rewritten s3 module to allow for additional modes of operation.
supervisorctl: add command-line options as module parameters

Adds more parameters which may be passed to supervisorctl:  config,
serverurl, username, password

Also refactored the various `module.run_command(build_a_string)` calls
into a single `run_supervisorctl` function.
Introduce exception AnsibleFilterError and use it in Jinja filters.  Ignore this exception when trying to find the name of a task for display (callback) purpose.
Only append non_unique parameter if a uid is provided as well
Let someone specify a path to a Rabbit that's not installed in the usual place.
Minor typo
Keystone_user module: fix authentication needs tenant_name too

The keystone client needs to be passed tenant_name when authenticating the
user/password way. Also it needs auth_url instead of endpoint.
This fix adds login_tenant_name as a module parameter which is consistent
with the other OpenStack modules.
digital_ocean: don't run update_attr if wait=no

Sometimes when using digital_ocean with wait=no I get the error "No ip is found".  But with wait=no I wouldn't expect there to be any IP, that gets allocated later.   However, looking at the code, it turns out that with even with wait=no it waits up to 10 seconds for an IP to be allocated.  We could wait longer, but with wait=no that seems like the wrong choice; it's easy enough to grab an IP later with a wait=yes command.

To make this change I removed the call to update_attr in @classmethod add.  An add is always followed by an ensure_powered_on which will do the update_attr if wait=yes.   It would be possible to instead do a call to update_attr with no retries and ignore the errors but I figured it would be better to be consistently not return an IP than to sometimes return it and sometimes not.   Inconsistent behaviour makes debugging deployment scripts very difficult.
digital_ocean doc update
update_attr should wait for the full wait timeout before checking for a missing IP addres
'prefix' avoids potentially making people confuse 'path' with $PATH.
supervisor_ctl: rename to server_url and improve documentation
Fix inconsistent json output

The file module would in some cases return dest=/path/to/file, and in other cases return path=/path/to/file, this change makes it more consistent and in line with all the other file-related modules (i.e. copy, assemble, template, ...) by using dest= instead of path= as the input and output argument. (Of course, path is still there as an alias for compatibility).
Added IAM role support
Update stat module to handle symlinks

Add follow parameter to stat module that controls whether to follow
symlinks.  It defaults to no.
This then calls os.stat or os.lstat based on the value of follow.
Add lnk_source key/value pair if path is a symlink and follow=no.
Drop the statement that sets isdir=False and islnk=True when path is a
symlink that points to a directory.
Introduce flat_list lookup plugin

- hosts: localhost
    gather_facts: False
    tasks:
    - debug: msg="{{item}}"
      with_flat_list:
      - a

        - d
        - - e
        - f
        - - g
          - h
      - i
      - j
      - - k
        - l

  # note: main list or list (sub)items can also be set as a variable
