convert: parse perforce data on-demand

We are using read-only attributes that parse the perforce data on
demand. We are reading the data only once whenever an attribute is
requested and use it throughout the import process. This is equivalent
to the previous behavior, but we are avoiding reading from perforce when
we initialize the object, but instead run it during the actual import
process, when the first attribute is requested (usually getheads(), see
`convertcmd.convert`).
