Test various backwards compatibility scenarios. Download the previous node binaries:
contrib/devtools/previous_release.sh -b v0.19.0.1 v0.18.1 v0.17.1
contrib/devtools/previous_release.sh -b v0.19.0.1 v0.18.1 v0.17.1 v0.16.3 v0.15.2
v0.15.2 is not required by this test, but it is used in wallet_upgradewallet.py.
Due to a hardfork in regtest, it can't be used to sync nodes.
Due to RPC changes introduced in various versions the below tests
won't work for older versions without some patches or workarounds.
