Update version for spring framework boot to 2.7.18

[thelarsjohansson]

Update spring framework boot version to 2.7.18.

Update to latest (and last) release on 2.7.* track in preparation of migration to Spring Boot 3.

@shroffk, if I am not mistaken we agreed that running the same version across the entire Phoebus stack is the preferred approach.

Also, with the recent changes for Spring Security in mind I'd like to avoid additional work when faced with new deprecations...

[shroffk]

Yes,
I think it just results in less effort. We are already standardizing the AA part which has deprecated parts of the security interfaces from 2.7 that we use.

During the next monthly meeting I am hoping we can put together a plan to move to spring 3

[thelarsjohansson]

The "upgrade" path should be Spring Boot 2.7.18 + Java 17, before the step to Spring Boot 3 (e.g. 3.2.2) is made. In general, it's suitable and standard behavior to update so as to make the upcoming leap as small as possible.

In addition

• Java 17 update already done
• 2.7.18 is update of minor version only

Therefore

• I recommend to update to Spring Boot 2.7.18 and use that as base for looking into Spring Boot 3.
