goth optimizations (discussion)

1. run agents asynchronously
2. try to setup central net, blockchain and constant components for all tests
3. don't build docker container at startup

We can pre-build docker container with all dependencies and at the first test just install proper version of yagna and other our (Golem Factory) artifacts. It should be instant. It will gain ~1 minute. Seems low hanging friut.

try to setup central net, blockchain and constant components for all tests
It's possible (and not too complicated) to keep the "static" network part (i.e. central net, blockchain, proxy) between tests.
However, this would fundamentally change the way we perform tests (we'd no longer have full isolation between test cases).
The time gained would be ~12 seconds per test case.

run agents asynchronously
The most time-consuming part of each test right now is waiting for yagna nodes to be ready. This takes ~20 seconds per node in each test. It's due to how the app keys are currently handled (in order to use the pre-funded Ganache keys we need to perform a restart of the daemon).
I can see two potential improvements here:

1. Improve how the keys can be loaded (identity pre-configuration or identity drop/update command).
2. Perform node setup in parallel in goth.

Re try to setup central net...) rather no-go for now
Re run agents async) Seems low-hanging fruit, and it needs joint effort from Core and SDK. Cool!

At our cyclic "make goth great" meeting we've discussed possible goth initialisation optimisation via #1539
which enables to use pre-funded Ganache keys without a hassle (start daemon, configure it, restart it).
It was added as golemfactory/goth#529
