Should start different database processes if using different --install-dir arguments

[e-gineer]

Describe the bug

If run twice with different --install-dir arguments then Steampipe should create separate DB instances.

Steampipe version (steampipe -v)

v0.4.0

To reproduce

/tmp $ steampipe --install-dir /tmp/a service start

Steampipe database service is now running:

  Host(s):  localhost, 127.0.0.1, 192.168.7.220
  Port:     9193
  Database: steampipe
  User:     steampipe
  Password: 519a-4b58-EXAMPLE

Connection string:

  postgres://steampipe:519a-4b58-EXAMPLE@localhost:9193/steampipe?sslmode=disable

Steampipe service is running in the background.

  # Get status of the service
  steampipe service status
  
  # Restart the service
  steampipe service restart

  # Stop the service
  steampipe service stop
