(install-and-migrate! conn schema-tx migrs)

Basic high-level utility for installing a Datomic schema and install migrations in an indempotent way.

conn should be a Datomic connection
schema-tx should be a Datomic schema installation transaction (will be run before the migrations, should be idempotent.)
migrs is a seq of maps, representing migrations to be run in order.

Each map of migrs should have the following properties:

:datofu.migration/id (required): a keyword, the id of the migration.
:datofu.migration/tx (required): a Datomic transaction request, to be run exactly once.
:datofu.migration/schema-tx (optional): a Datomic transaction request, installing a schema specific to this transaction. (will be run before the migrations, should be idempotent.)

The migrations are run one after the other (since a migration may rely on the state of the database after a previous migration).

The goal of this function is to easily sync a Datomic system to a given codebase.
