Fix dependencies graph for minio source compilation (#8717)

We had messy cyclical dependency problem with `mc`
due to dependencies in pkg/console, moved the pkg/console
to minio for more control and also to avoid any further
cyclical dependencies of `mc` clobbering up the
dependencies on server.

Fixes #8659

pkg/console/console_test.go
