Enable Setup/Update of OIDC Auth for Arkime Portal

[chelma]

Description

UPDATED DESCRIPTION:
As part of enabling OIDC auth (#75), we want to enable users to setup OIDC Auth on the Arkime Portal. To do this, we should update our README with clear instructions on how to update the Arkime and other configuration, how to stick the OIDC secret in SecretsManager and retrieve it in the container, etc.

This task assumes the completion of #80

OBSOLETE DESCRIPTION:
As part of enabling OIDC auth (#75), we want to enable users to setup OIDC Auth on the Arkime Portal. To accomplish this, we will need to support one or more new CLI commands to allow them to pass in the necessary configuration and pipe it through to the containers.

This task assumes the completion of #76

Acceptance Criteria

• User is able to perform initial configuration of OIDC Auth
• User is able to update their initial OIDC Auth configuration
• Demo'd with a real OIDC provider

Updating task description based on design discussion in this RFC (#81). We no longer want separate commands for this.
