Description

When upgrading a Sling instance, some bundles that were previously installed by the BootstrapInstaller might need to be removed.

The BootstrapInstaller can currently update bundles, but not remove them.

To implement this in an extensible way, we can add a sling_bootstrap.txt command file that is processed by the BootstrapInstaller once at startup, as follows:

1. sling_bootstrap.txt is found at the root of the sling home folder
2. If it exists, it is executed if its timestamp is greater than the one stored by the BootstrapInstaller
3. The file contains commands to uninstall bundles, we can add new commands later if needed
4. BootstrapInstaller stores a new timestamp after executing the file

1. sling_bootstrap.txt example
2. comments and blank lines are ignored
   uninistall org.apache.sling.somebundle 1.0.4

1. VersionRanges are supported
   uninistall org.apache.sling.otherbundle [1.1, 1.2)
