* uplink: Add a new flag to set the filepath of the file which is used for
saving the encryption key and rename the one that hold the encryption key and
establish that it has priority over the key stored in the file to make the
configuration usable without having a huge refactoring in test-sim.
* cmd/uplink: Adapt the setup subcommand for storing the user input key to a file
and adapt the rest of the subcommands for reading the key from the key-file when
the key isn't explicitly set with a command line flag.
* cmd/gateway: Adapt it to read the encryption key from the key-file or use the
one passed by a command line flag.
* pkg/process: Export the default configuration filename so other packages which
use the same value can reference to it rather than having it hardcoded.
* Adapt several integrations (scripts, etc.) to consider the changes applied in uplink and cmd packages.
* test-network-stalls tests... network stalls!
in particular, right now, it just tests whether an uplink correctly
times out after some amount of time when one of the nodes it's talking
to suddenly goes offline.
This tool is meant to be run under `storj-sim network test`.
Also included here:
* fix storj-sim-related test scripts on Mac
the default storj config dir on Mac has a space in it
('~/Library/Application Support/Storj'), which breaks everywhere it
shows up in an unquoted variable in a sh/bash script. easy enough to fix
as a one-off, but quoting bash vars avoids a dozen other potential
problems too.
change a few things using `head -c` to use `dd`. `head -c` works,
but is not as widely understood (as evidenced by each of these scripts
getting through code review, one at a time, with the comments not
matching the numbers actually used).
* storj-sim reports PIDs of worker processes to test
so that the tests can cause unfortunate "accidents" to befall the worker
processes in the course of the test, and find out whether everything
reacts correctly.
* initial wireup of test script
* making some progress
* working on getting gateway config to work
* get script working for testing uplink
* removes unnecessary stuff
* more removal of unnecessary change
* remove unnecessary pointerdb set in setup
* fix dest dir in test-aws script
