[Feature]: change the way handling Package Manager Config on IT

[kpanot]

Context

Today in IT, we need to target a local registry to download the current version of the packages to test. To do so, we create (set config commands) the .npmrc and .yarnrc.yml file within the folder containing the environment in which we process tests.

To avoid creating a Package Manager configuration in each project, we can set the configuration in a custom user configuration. Currently npm provide an option to set configuration in a custom User configuration but not yarn which force the User configuration to be in ~/.yarnrc.yml.

Proposal

A solution is to redifine the homedir variable at Node level for run of IT test.
