$params can take an optional 'skip_modzebra_update' parameter.
If set, the reindexation process will not happen (ModZebra not called)

NOTE: This is a temporary fix to answer a performance issue when lot of items
are added (or modified) at the same time.
The correct way to fix this is to make the ES reindexation process async.
You should not turn it on if you do not understand what it is doing exactly.

=head3 can_be_transferred

$item->can_be_transferred({ to => $to_library, from => $from_library })
Checks if an item can be transferred to given library.

This feature is controlled by two system preferences:
UseBranchTransferLimits to enable / disable the feature
BranchTransferLimitsType to use either an itemnumber or ccode as an identifier
                         for setting the limitations

Takes HASHref that can have the following parameters:
    MANDATORY PARAMETERS:
    $to   : Koha::Library
    OPTIONAL PARAMETERS:
    $from : Koha::Library  # if not given, item holdingbranch
                           # will be used instead

Returns 1 if item can be transferred to $to_library, otherwise 0.

To find out whether at least one item of a Koha::Biblio can be transferred, please
see Koha::Biblio->can_be_transferred() instead of using this method for
multiple items of the same biblio.

=head3 pickup_locations
