Merge branch 'feature/ci_checkout_same_branch_for_submodule' into 'master'

Feature/ci checkout same branch for submodule

esp-idf have several submodules like wifi-lib, bt-lib.

esp-idf branches may need to use specific branches in submodules to get build pass and do test.

This feature will first try to checkout the branch with same name for all submodules for jobs which uses global `before_script`
