Gaia is removed from cosmos-sdk repository. Few changes were required to make sure no packages depend on gaia subpackages. CI config is amended accordingly. Unnecessary targets are removed from Makefile. Simulations run through a lightweight version of gaia renamed to simapp. Closes: #4104
Generally we should avoid shell scripting and write tests purely in Golang. However, some libraries are not Goroutine-safe (e.g. app simulations cannot be run safely in parallel), and OS-native threading may be more efficient for many parallel simulations, so we use shell scripts here.
