git creds are not used when install packages

Context

• An experiment lives in a private repo
• agent.git_user and agent.git_pass are configured in trains.conf
• This experiment is a python package installed at runtime
• This python package has dependencies
• Among the dependencies, one is another private repository

Problem

trains-agentwill successfully clone the private repo where the experiments lives using the git credentials configured. But it will fail installing the dependencies, because one of them is a private repo and trains-agent won’t use the configured git credentials for the installation of the dependencies.

Solution

trains-agent should use the git credentials for any git operation, regardless of when it happens.

@H4dr1en yep 😃 Should work with trains-agent==0.15.1

@H4dr1en makes total sense 😦 I think we will have to make sure we pass the correct git credentials for pip. This means trains-agent will take this line:

my-dependency-package @ git+https://github.com/H4dr1en/my-dependency-package@92kv9gk3b1cabf08a0b45d87fk3e70bd73a7bc94

and will pass to pip this line instead:

my-dependency-package @ git+https://user:[e-mail]/H4dr1en/my-dependency-package@92kv9gk3b1cabf08a0b45d87fk3e70bd73a7bc94
