The required number of licenses have been acquired from the license source.
This indicates that the license has expired or the system attempted to acquire
the license but was not successful in reserving it.
This license is currently unused by the system, or the feature does not
apply. For example, a DRS license appears as NotUsed if the host is not
part of a DRS-enabled cluster.
The LicenseManager failed to acquire a license but the implementation
policy allows us to use the licensed feature anyway. This is possible, for
example, when a license server becomes unavailable after a license had been
successfully reserved from it.
