Migrate pre-main-check-users-map to Github action

[Sawthis]

Description

Create a Cloud Run service that will generate a file in Google Cloud Firestore containing Slack user mappings. Below is the relevant code snippet that demonstrates the function:

from slack_sdk import WebClient
from slack_sdk.errors import SlackApiError

with open('/etc/slack-secret/common-slack-bot-token-test', encoding='utf-8') as token_file:
    slack_bot_token = token_file.readline()

slack_client = WebClient(token=slack_bot_token)

def get_slack_user_mapping():
    '''Fetches Slack users and returns a mapping of real names to Slack IDs'''
    try:
        users = {}
        cursor = None
        while True:
            response = slack_client.users_list(cursor=cursor)
            for member in response['members']:
                real_name = member.get('real_name')
                slack_id = member.get('id')
                if real_name and slack_id:
                    users[real_name] = slack_id
            cursor = response['response_metadata'].get('next_cursor')
            if not cursor:
                break
        return users
    except SlackApiError as e:
        print(LogEntry(
            severity="ERROR",
            message=f"Error fetching Slack users: {e.response['error']}",
            **prepare_log_fields(),
        ))
        return {}

The Cloud Run service should be configured to:

• Work with a scheduler to ensure regular updates.
• Respond to triggers from other Cloud Run services, allowing it to be invoked on demand or periodically.

Additionally, modify the SlackMessageSender Cloud Run / GitHub-webhook-gateway Cloud Run to:

• Use the file stored in Firestore to identify users.

If a user is not found, the application should invoke the above Cloud Run service to reload the file and confirm it has completed the operation.

• This can be verified by comparing the number of lines, words, or characters in the fetched file.
  • If the new file contains more content, it indicates a successful reload.
  • If not, the system should wait until the Cloud Run service completes its task, considering potential rate limits.

Reasons

Migration out from Prow.

Acceptance Criteria

• [ ] The functionality is executed on the internal GitHub.
• [ ] The pre-main-check-users-map Prow job is removed.
• [ ] Create a slackusermapping-cloudrun service to pass the file to Google Cloud Firestore.
• [ ] Modify the SlackMessageSender Cloud Run / GitHub-webhook-gateway Cloud Run to use the file from Google Cloud Firestore.
