Consider possibility exclude PropertySourcesPlaceholderConfigurer in RedisHttpSessionConfiguration in version 1.3.x

[andreytkachuk31]

Conditions:
We used spring-session module of version 1.1.x. And we had own PropertySourcesPlaceholderConfigurer bean with field ignoreUnresolvablePlaceholders=true configured with <context:property-placeholder ignore-unresolvable="true">

Issue:
We had to upgrade spring-session to 1.3.x version. We did it and we tried to run application but we got exception, because our unresolved properties were failed. It happened because there is RedisHttpSessionConfiguration in 1.3.x version and this configuration declares PropertySourcesPlaceholderConfigurer bean with field ignoreUnresolvablePlaceholders = false.

Could you consider possibility exclude or make optional bean PropertySourcesPlaceholderConfigurer in class RedisHttpSessionConfiguration in spring-session module of 1.3.x version?

@andreytkachuk31 Thanks for the report.

@vpavic I am wondering if the best approach would be ignore unresolved properties. Thoughts?

We've removed the use of PropertySourcesPlaceholderConfigurer in Spring Sesion 2.0 via #907 and #910.

For 1.3, this is basically a duplicate of #867 - @andreytkachuk31, can you take a look at this comment and see if the proposed workaround helps?

@rwinch @vpavic Proposed workaround helps. Thanks!
