This PR introduces a base cost charged to each canister, in addition to the existing cost for a canister's memory footprint. The cost is 10k cycles/s, which is roughly 0.026T cycles/month.

There was a problem hiding this comment.
Idly wondering: This just occurred to me, after having gone through more than half the PR. Wouldn't it be simpler (at least for the tests not focused on charging) to set the base fee to zero?

This PR introduces a base cost charged to each canister, in addition to the existing cost for a canister's memory footprint. The cost is 10k cycles/s, which is roughly 0.026T cycles/month.
The motivation is to correctly account for the fact that canisters cause overhead, even if they have a small memory footprint.
