Is your feature request related to a problem? Please describe.
There is no support to pass the certificate as a string directly while using the Relay Proxy. We can only pass the certificate file path. In Go library, though, we can directly pass the certificate key or use the file path option while using the Relay Proxy.

Description in the code which requires us to pass the path to the certificate file

Method from the Go SDK which allows us to pass the certificate as a bytes array

Describe the solution you'd like
Is there a plan to add the support to pass the certificate as a string/binary date while using the Relay Proxy in Python SDK? It looks like this support can be added by upgrading the urllib3 library version to >=2.0.0.
