feat: --start-server should support API prefix settings

[louis-jan]

Problem Statement

Currently, when starting the cortex-server with the attached mode using the --start-server option, you can specify the following parameters:

• host
• port
• config_file_path
• data_folder_path

It would be beneficial to have the option to set server API prefix settings to change the default /v1. Currently, Jan supports this API server setting.

Another setting that would truly be beneficial is to configure the log file path, where Jan could simply route all log outputs into a single file.

Feature Idea

AC1:

Given that I have cortex-server installed,

When I start the cortex server using the --start-server command,

Then I can specify the --api_prefix argument to set the API prefix path, for example, /v1.

As a result, I will observe that the server serves endpoints at the configured path.

AC2:

Given that I have cortex-server installed,

When I start the cortex server using the --start-server command,

Then I can specify the --log_path argument to set the log path for the cortex server.

As a result, I will see that the server outputs logs to the specified path.
