Set SNI on SSL connections #634
Description
Feature Request
Is your feature request related to a problem? Please describe
Some SSL-aware proxies relies on the SNI to route connections[1]. Also, libpq sends SNI by default[2]. I think it's better for r2dbc-postgresql to provide an option to support SNI as well.

Describe the solution you'd like
IMO, there should be an option to control the behavior, for example a global / per connection, and turn it on by default to be aligned with libpq, and then the lib sets SNI accordingly in the createSslProvider.
