chore: update alpine base to 3.24 in kapacitor and chronograf

[karel-rehor]

In alpine Dockerfiles for kapacitor and chronograf, the base image is now set to the 3.24 release.

Smoke tested each new image locally with

• a local docker build
• run of the built image
• verification of normal startup
• in chronograf checked the UI wizard updated with "Welcome to the latest Chronograf..." message

for example.

$ cd ../../1.9/alpine/
$ docker build --tag chronograf:1.9-alpine-local .
$ docker run --name chronograf-1.9-alpine-test -p 8888:8888 chronograf:1.9-alpine-local
# verify application load in browser... 
$ docker rm chronograf-1.9-alpine-test 
$ docker rmi chronograf:1.9-alpine-local 
$ cd ../../1.10/alpine/

Thanks for the PR! It seems like this should be limited to currently supported releases and not historic. @srebhan - thoughts?

Also, what about influxdb, which was also listed in docker-library/official-images#21630 (comment)?

[srebhan]

I agree with @jdstrand that we should not update all versions. I would even extend this and request to update the base image with the next release of both Chronograf and Kapacitor to keep the existing images stable.

See #884 and #885 to remind us on the required update.

@karel-rehor what do you think?
