/**
* Service for managing the initial provisioning information.
*
* Initial provisioning of an OSGi device is a multi step process that
* culminates with the installation and execution of the initial management
* agent. At each step of the process, information is collected for the next
* step. Multiple bundles may be involved and this service provides a means for
* these bundles to exchange information. It also provides a means for the
* initial Management Bundle to get its initial configuration information.
*
* The provisioning information is collected in a {@code Dictionary}
* object, called the Provisioning Dictionary. Any bundle that can access the
* service can get a reference to this object and read and update provisioning
* information. The key of the dictionary is a {@code String} object and
* the value is a {@code String} or {@code byte[]} object. The
* single exception is the PROVISIONING_UPDATE_COUNT value which is an Integer.
* The {@code provisioning} prefix is reserved for keys defined by OSGi,
* other key names may be used for implementation dependent provisioning
* systems.
*
* Any changes to the provisioning information will be reflected immediately in
* all the dictionary objects obtained from the Provisioning Service.
*
* Because of the specific application of the Provisioning Service, there should
* be only one Provisioning Service registered. This restriction will not be
* enforced by the Framework. Gateway operators or manufactures should ensure
* that a Provisioning Service bundle is not installed on a device that already
* has a bundle providing the Provisioning Service.
*
* The provisioning information has the potential to contain sensitive
* information. Also, the ability to modify provisioning information can have
* drastic consequences. Thus, only trusted bundles should be allowed to
* register and get the Provisioning Service. The {@code ServicePermission}
* is used to limit the bundles that can gain access to the Provisioning
* Service. There is no check of {@code Permission} objects to read or
* modify the provisioning information, so care must be taken not to leak the
* Provisioning Dictionary received from {@code getInformation} method.
