Charles Ferguson 490038b0e4 Update documentation of the 'pkg' and 'state' parameters in yum. 
The yum module allows the 'name' parameter to be given as 'pkg', in
a similar way to some of the other package managers. This change
documents this alias.

The module's 'state' parameter has two other aliases, in line with
the 'apt' action; the 'state' parameter can take 'installed' as an
alias for 'present', and 'removed' as an alias for 'absent'. These
aliases are documented.

notes:
- When used with a loop of package names in a playbook, ansible optimizes
the call to the yum module. Instead of calling the module with a single
package each time through the loop, ansible calls the module once with all
of the package names from the loop.
- In versions prior to 1.9.2 this module installed and removed each package
given to the yum module separately. This caused problems when packages
specified by filename or url had to be installed or removed together. In
1.9.2 this was fixed so that packages are installed in one yum
transaction. However, if one of the packages adds a new yum repository
that the other packages come from (such as epel-release) then that package
needs to be installed in a separate task. This mimics yum's command line
behaviour.
- 'Yum itself has two types of groups. "Package groups" are specified in the
rpm itself while "environment groups" are specified in a separate file
(usually by the distribution). Unfortunately, this division becomes
apparent to ansible users because ansible needs to operate on the group
of packages in a single transaction and yum requires groups to be specified
in different ways when used in that way. Package groups are specified as
"@development-tools" and environment groups are "@^gnome-desktop-environment".
Use the "yum group list" command to see which category of group the group
you want to install falls into.'
