Add support to load multiple CA certs from store

[dsimansk]

It'd be great to add a support for multiple CA certs.

In fact it's a bug affecting latest versions of OpenShift. The same issue was fixed in openshift-ping.

Valid point, thanks for spotting this ! Not sure whether you want to send in a PR, but if so, I could release the next version of jolokia over the weekend.

[dsimansk]

@rhuss I've created a PR, please take a look when it suits you. It's not so urgent as there's another issues on the OpenShift side. However, it might be good to have this one resolved just in case. :)

[rhuss]

Thanks a lot ! I will have a look ASAP, also because I guess it will take a bit until it bubbles up to the images using Jolokia. So I agree, that Jolokia should be ready soon.

Hi Roland!

Do you have plans for a release anytime soon? We'd like to use this functionality for OpenShift 4 related setups.

[rhuss]

@paoloantinori I have no concrete plans but can do a release soonish. If there won't be a release until the end of the week, please ping me again.

thank you!
