[validation] [Spring Security] Lambda DSL

[BoykoAlex]

See Lamda DSL - Spring Security documentation.

A recipe marking old syntax with warning or info and a quick fix (Rewrite recipe) converting old syntax into a new lambda DSL would be great.

Markers are in: 6979975
Fix proposals are missing and would need work done in rewrite-spring project. Once recipes are completed they would be adopted in STS Boot LS and then the issue would be completed.

Should be fixed with dccf860
