Add more appcmd commands

[spuder]

Placeholder issue to add more appcmd commands.
#208 (comment)

appcmd supports all of the following.

• list

• set

• search

• lock (already implemented in the iis_section resource)

• unlock (already implemented in the iis_section resource)

• clear

• reset

  By default, the configuration is reset at the server level, but you can also specify a specific configuration level to reset. Example: appcmd reset config ["configPath"] /section:SectionName

• migrate

Some of these would probably never be used. lock, unlock , list and maybe reset are the more useful of the bunch.

definitely love this idea, feel free to add them in small commits or whole groups. Let me know, i'm going to start working on the DSC branch that was requested.
