Previously the MongoDB health indicates used Spring Data's templates
(imperative and reactive) to access MongoDB. This prevented health
information from being available in apps using Mongo's Java Driver
directly.
This commit updates the health indicates so that they no longer
depend upon Spring Data MongoDB and instead using MongoDB's Java
Driver directly. As they no longer depend on Spring Data MongoDB,
the indicators have also moved from spring-boot-data-mongodb to
spring-boot-mongodb.
Closes gh-47051
GridFS is a concept specific to Spring Data MongoDB while
MongoConnectionDetails provides general details for connecting to
MongoDB, with or without Spring Data MongoDB. As such GridFS does not
belong on MongoConnectionDetails and this commit removes it.
Support for configuring GridFS through properties remains.
Closes gh-47044
