Cassandra multiple hosts cluster migrations failed

[easokol]

Describe the Bug
Unable to perform migrations on Cassandra multiple hosts cluster

Steps to Reproduce
Steps to reproduce the behavior:

1. Assume we have Cassandra cluster with 3 replicas replica1,replica2,replica3, hosts can be resolved and reached correctly.
2. migrate -verbose -path=migrations -database "cassandra://replica1:9042,replica2:9042,replica3:9042/base?consistency=ALL" up
3. See error error: gocql: unable to create session: failed to resolve any of the provided hostnames

Expected Behavior
Migrations successful as with PostgreSQL, MongoDB, etc

Migrate Version
4.17.0

Loaded Source Drivers
Source drivers: bitbucket, gitlab, godoc-vfs, s3, gcs, go-bindata, file, github, github-ee

Loaded Database Drivers
Database drivers: stub, clickhouse, cassandra, mysql, pgx4, crdb-postgres, firebird, pgx5, cockroach, cockroachdb, mongodb+srv, sqlserver, spanner, pgx, postgres, yugabyte, rqlite, mongodb, firebirdsql, postgresql, redshift, yugabytedb, ysql, neo4j

Additional context
There is issue with gocql gocql/gocql#1509
But seems to be Migrate does not correctly support multiple hosts, they should be split to multiple args while call gocql.NewCluster()

migrate/database/cassandra/cassandra.go

Line 97 in 87ba13c

cluster := gocql.NewCluster(u.Host)
