Description

The indexing tooling implemented in OAK-6081 can be used to perform reindex and import the indexes for any Oak 1.7+ setups. For older setups we would be using 2 phase approach

1. Perform out-of-band indexing. This can be done via oak-run from 1.7.x against any older version of Oak
2. Import index - For this step we cannot use oak-run from trunk for older branches as write operations would not be compatible with older version of Oak.

For import then we have 2 options either

1. backport all the work in OAK-6271 to older branch
2. OR implement a script which can be used with oak-run or Felix Script Console to just import the lucene index with any other manual step

Purpose of this task is to implement such a script

Note - The proposed script is meant to be run from within running Oak server using Felix Script Console [1]. This is required as older version of oak-run do not support all types of BlobStores
