Support for migration to a new silecs version

Here how it was done in the eclipse plugin:

https://gitlab.com/al.schwinn/silecs-eclipse-plugin/-/blob/RestructureSilecsDeploy/silecs-eclipse-plugin/src/java/silecs/view/job/UpdateVersionJob.java

(Note that migration only will be required, if there are actually new silecs versions available)

During install of most recent silecs plugin (file:/common/usr/cscofe/silecs/silecs-eclipse-plugin-gsi-update-site):

Tested with:

acc8: eclipse-2020-06 eclipse-2021-06 acc7: eclipse-2020-06

added silecs-cli label

Probably sufficient to use replace the old version with the new one via sed
