…#12772)

Add in the caching mechanism to the Satellite's api property (#12765)

This should have always existed but was overlooked. It will dramatically
decrease the amount of time it takes to access the api property since
it doesn't need to be reconstructed each time the property is accessed.

Before
------
%timeit mysat.api.Host
3.62 ms ± 52.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

After
-----
%timeit mysat.api.Host
189 ns ± 0.943 ns per loop (mean ± std. dev. of 7 runs, 10,000,000 loops each)

(cherry picked from commit b3d32b6)
