feat: specify port binding for docker

[lvrach]

Description

Motivation

We have been facing overlapping issues with ipv4 ipv6 ports, causing tests to fail randomly. You can read more about the issue here.

This PR attempts to solve the problem differently by providing a cleaner solution.

Solution

We use port bindings to only bind to ipv4 host address.

Changes

Provide Host

control host for downstream libraries:

• use src.GetBoundIP instead of hardcoding localhost
• export URL or address (host:port) instead of just port

This gives us more control over ipv4 vs ipv6 if needed. It would allow us to use external docker hosting.
In most cases, it simplifies consumers of the API

defaults

PublishAllPorts = false Only publish ports being mentioned explicitly.

Don't we need to set PublishAllPorts to false?

postgresContainer, err := pool.RunWithOptions(&dockertest.RunOptions{
		Repository: "postgres",
		Tag:        c.Tag,
		NetworkID:  c.NetworkID,
		Env: []string{
			"POSTGRES_PASSWORD=" + postgresDefaultPassword,
			"POSTGRES_DB=" + postgresDefaultDB,
			"POSTGRES_USER=" + postgresDefaultUser,
		},
		Cmd:          cmd,
		PortBindings: internal.IPv4PortBindings([]string{"5432"}),
	}, func(hc *dc.HostConfig) {
		hc.ShmSize = c.ShmSize
		hc.OOMKillDisable = c.OOMKillDisable
		hc.Memory = c.Memory
	},
		internal.DefaultHostConfig,
	)

Do we need to set PublishAllPorts to false in sshserver.go and transformer.go as well?

We should set PublishAllPorts to false in all the resources and expose ports only via port binding.
