Implementation Details

Point 1: change logger prefix to persistence-loader

The prefix of entrypoint has been changed from:

INFO - entrypoint - 2023-08-04 18:02:33,256 - Creating tables (if not exist)
INFO - entrypoint - 2023-08-04 18:02:33,327 - Updating schema (if required)
INFO - entrypoint - 2023-08-04 18:02:33,461 - Creating indexes (if not exist)
INFO - entrypoint - 2023-08-04 18:02:33,676 - Importing builtin LDIF files

to

INFO - persistence-loader - 2023-08-04 18:02:33,256 - Creating tables (if not exist)
INFO - persistence-loader - 2023-08-04 18:02:33,327 - Updating schema (if required)
INFO - persistence-loader - 2023-08-04 18:02:33,461 - Creating indexes (if not exist)
INFO - persistence-loader - 2023-08-04 18:02:33,676 - Importing builtin LDIF files

Point no. 2: allow executing entrypoint.sh from any directory or by using symlink

The entrypoint.sh can be executed from any directory. Also it support symlink, for example:

ln -s /app/scripts/entrypoint.sh /app/bin/persistence-loader-entrypoint.sh
sh /app/bin/persistence-loader-entrypoint.sh
