 This change introduces a new method, providing a generic way to act on slivers in an AM or resource type specific way. This method shall be used to 'start' or 'stop' or 'restart' resources that have been allocated but not started by !CreateSlivers or !RedeemTicket. It may also be used to change the state of slivers (or their contained resources) in an aggregate or resource specific way. Some aggregates may use this method to change configuration details of allocated resources. This might include changing acceptable login keys.
 
-!ActOnSlivers takes a {{{command}}}, {{{urn}}}, {{{state}}}, and {{{options}}}. The method return is a struct that includes the {{{urn}}}, {{{geni_status}}} of the sliver(s), and any other AM and operation specific options. The URN may be a slice urn, meaning all slivers in that slice at this AM are effected. Or the URN may be a particular sliver URN. The {{{state}}} argument is one of the {{{geni_status}}} values, or an AM-specific value. The {{{state}}} meaning depends on the {{{command}}}, but typically indicates the desired or resulting new state of the sliver(s). If the AM wishes to return an aggregate specific sliver status, it should still return a valid {{{geni_status}}}, and use an additional entry to also return the aggregate specific state. The {{{command}}} argument is aggregate defined. This API does not specify how aggregates advertise valid commands. Three particular commands are typical however: {{{start}}}, {{{stop}}}, and {{{restart}}}. These are used when the {{{geni_donotstart}}} option is supplied to !CreateSlivers for example.

+Three particular commands are specified however: {{{start}}}, {{{stop}}}, and {{{restart}}} (case insensitive). If an aggregate provides resources which require an explicit action to make {{{allocated}}} resources {{{ready}}} for experimenter use (booting, applying a configuration change) then the aggregate must make that operation available using these commands. These commands are used when the {{{geni_donotstart}}} option is supplied to !CreateSlivers for example.
