[IMP] api: lazy_property for user, company, companies

These variable are not supposed to change within a same
environment.

The lazy property will compute these variables only
once, then store the result,
while the property were computing these variables
each time they were called.

e.g. for a 1000 iteration loop,
with `env.company`,
the company was computed 1000 times.
With a lazy property, the company will be computed one time only.
