### Is there an existing issue for this?

### Current Behavior

I am running a script to set up a local stack environment. When running the following commands there is an issue with Redis and MySQL fighting for the same port. 
```
echo "Create an Mysql RDS Instance"
awslocal rds create-db-instance \
    --db-instance-identifier devops-toolkit \
    --db-instance-class db.t3.micro \
    --engine mysql \
    --master-user-password 12345678 \
    --master-username admin \
    --allocated-storage 5
sleep 5
echo "Create a Redis Cache Cluster"
awslocal elasticache create-cache-cluster --cache-cluster-id cluster-1
```
This can be seen in the logs
```

```
And then results in mysql errors
```
ERROR: 'cat /tmp/tmpfbw8o1x_ | mysql --socket /tmp/mysql-states/09a73ec8/mysqld.sock': exit code 1; output: b"ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql-states/09a73ec8/mysqld.sock' (2)\n"
```
Any ideas, thanks in advance ✌️ 

### Expected Behavior

The two services should be run on different ports, is the the possibility to preconfigure the port on which each service is run?

### How are you starting LocalStack?

With the `localstack` script

### Steps To Reproduce

Run this simple script
```
localstack start -d
echo "wait for local stack to start"
sleep 10
echo "Now trying to configure local stack"
echo "Create an Mysql RDS Instance"
awslocal rds create-db-instance \
    --db-instance-identifier devops-toolkit \
    --db-instance-class db.t3.micro \
    --engine mysql \
    --master-user-password 12345678 \
    --master-username admin \
    --allocated-storage 5
sleep 5
echo "Create a Redis Cache Cluster"
awslocal elasticache create-cache-cluster --cache-cluster-id cluster-1
```

### Environment

```markdown
- OS: MacOS 11
- LocalStack: latest
```
