SOCKS5 proxy support

**Is your feature request related to a problem with the Vault plugin for Redis? Please describe.**

When using the Vault plugin for Redis with a SOCKS5 proxy, users encounter connectivity issues. Although the `HTTP_PROXY` and `HTTPS_PROXY` environment variables support the `socks5://` URL scheme for SOCKS5 proxies, the Redis plugin doesn't currently support this feature.

**Describe the solution you'd like**

To provide a consistent proxy support experience across all Vault components, I would like the Vault plugin for Redis to be updated to support the `socks5://` URL scheme for `ALL_PROXY`.

**Describe alternatives you've considered**

As a workaround, users may have to set up additional proxy layers or workarounds to connect to Redis through a SOCKS5 proxy, which can be cumbersome and time-consuming.

**Explain any additional use-cases**

Support for SOCKS5 proxies in the Vault plugin for Redis would benefit users who require secure and flexible proxy configurations for their Redis databases, enabling them to use Vault more effectively.

**Additional context**

Lack of SOCKS5 proxy support in the Vault plugin for Redis creates limitations in connectivity and requires additional workarounds. By implementing consistent proxy support across Vault components, we can enhance the user experience and increase the flexibility of Vault for connecting to Redis databases.
