Add an ability to log SQL queries executing in JdbcTemplate class provided by JdbcPollingChannelAdapter class when debug is enabled.

[morozovivan95]

Affects Version(s): 5.1.2.RELEASE

There is a log message written in JdbcTemplate starting with "Executing prepared SQL statement", but it remains not continued with actual SQL query being executed due to the fact that JdbcPollingChannelAdapter does not implement SqlProvider interface.

Are there any significant reasons not to provide this functionality which leads to absence of such an important debug information?

Thank you for the report, @morozovivan95 !

I found similar problem in the JdbcMessageHandler.
Wasted time to figure out how to simplify our code over there, but looks like there is just on way with the current JdbcTemplate API...
