Upgrade to Embedded Mongo 3.4.2

As part of the upgrade, the property for configuring features has
been removed as support for feature-aware versions has been removed
from Embedded Mongo. For advanced configuration where features were
specified, users should provide a MongodConfig bean instead.

Closes gh-29985
Closes gh-30219
