ContextResource that supports auto-context

[alexanderlazarev0]

Right now, a context always needs to be initialized before resolving a providers.ContextResource:

with my_context_resource.sync_context():
    my_context_resource.sync_resolve():

It would be great to support automatically initializing a context when one attempts to resolve a context-resource:

my_context_resource = providers.ContextResource(my_sync_creator, auto_context=True)

my_context_resource.sync_resolve() # `Does not throw Exception`
