Add configuration option to enable/disable automatic index creation. [DATAMONGO-2188]

[spring-projects-issues]

Mark Paluch opened DATAMONGO-2188 and commented

Over time, we found that our auto-index creation feature causes more downstream issues than it actually solves. We constantly get requests to customize indexing in the sense of requirements that oppose each other.

The underlying issue is that indexing requires a lot of customization in terms of index definition and the time at which indexes are created. We're going to deprecate this feature and recommend using the API to derive/create index definitions and to use the API to create actually indexes.

Spring Data MongoDB does not aim for being a DDL tooling but rather improve development efficiency
