This is a workaround for IAR's lack of flexibility with memory regions.
Otherwise these tests would use very little heap and be mostly global
allocations.
This matches the timeout used in linux:
https://linux.die.net/man/5/dhclient.conf
This resolves several issues noticed during testing when we
have a very large number of devices that try to get an IP address
around the same time.
Reduce RAM consumption so all tests can still be built when using
CMSIS/RTX5. Also reduce clutter by removing the per target stack size
defines in the tests.
Sometimes when under heavy load, the CI machines can take a significant
amount of time to bring up a python process (~10s). The timeouts for
the network tests were chosen without much thought, and didn't leave
much room for this sort of delay.
This patch brings up timeouts for ntetwork tests 20s -> 60s
This commit reduces the thread stack from 2k to 1k for each thread in
the parallel network tests. This allows the test to run on more
constrained devices (like the LPC1768).
These tests could adopt the dynamically sized buffers used for the
packet-pressure tests, however throughput is not an important feature
of these tests.
