Feature Request: Enhance Valkey Testcontainer with Custom Configuration and Latest Image Support

Description

Enhance the testcontainers-rust Valkey module to support additional configuration methods and improve flexibility in test environments.

Proposed Features

1. Support for Custom Valkey Configuration Using Extra Flags

   • Allow users to pass additional command-line flags to the Valkey container.
   • Example:

     Valkey::default().with_valkey_extra_flags("--maxmemory 2mb")

2. Support for Custom Valkey Configuration Using a Custom valkey.conf

   • Enable users to mount a custom valkey.conf file into the container.
   • This allows for more complex and persistent configurations.
   • Example:

     Valkey::default().with_valkey_conf("maxmemory 2mb".to_string().into_bytes(),)

3. Support for the Latest Image Tag

   • Provide an option to use the latest available Valkey Docker image (valkey/valkey:latest).
   • Ensure compatibility with the latest Valkey features without requiring manual tag updates.
   • Example:

     Valkey::latest()

Motivation

These improvements allow for greater flexibility when using Valkey in integration tests, enabling developers to:

• Leverage advanced Valkey features.
• Ensure compatibility with specific configurations.
• Test against the latest Valkey versions easily.
