[TASK] Allow DI based services in localconf during extension install

We fix PackageManager and ContainerBuilder to allow
multiple container instances (including multiple
cache identifiers) to be live.
ExtensionManager will now load a new symfony container
after installing a new extension, and before reloading
all ext_localconf files. We need to ensure that possible
services in ext_localconf can be loaded when they
depend on symfony DI.

Note: This is not a BUGFIX as this was never
supported for extensions. But it may lead to hard-to-debug
bugs when extension developers add a service to ext
localconf but do not test the re-installation procedure
before publishing the extension to TER.
