Provide an option to specify a file to perform the neo4j-migrations (--location)

Neo4j-Migrations versions (tried 3 versions): 1.6.0, 1.8.0, 1.8.3. Used Neo4j-Migrations tool via CLI (Neo4j-Migrations-CLI).

The command that was used: neo4j-migrations --username {user_name} --password {password} --address bolt://{IP}:7687 --database entitlements --location file:./scripts migrate

In location, I can only specify a folder, but I want to specify a filename within a folder. For example: neo4j-migrations --username {user_name} --password {password} --address bolt://{IP}:7687 --database entitlements --location file:./scripts/V1_1_1__v1_constraints.cypher migrate

I see the message: No migrations have been applied.

And what should happen when you want to add a 2nd file? Shall the tool create a migration graph? Or append to the existing one?

It would require the whole validation to be rewritten. If you just want to run scripts, Neo4j Cypher-Shell is a better option. The scripts will be compatible.

Hi @michael-simons

I would expect to add a node to an existing one. I understand that this is not a common use case, but for our particular case, it would be nice if we had the option.

I'm gonna pick this up later this week, will most likely not add anything to the chain, but just run a cypher or catalog based migration and be done with it. This way refactorings can be used easily standalone.
