…uirements for rapid Docker startup. (#45269)

Related PR: #45267

Problem Summary:

To meet the needs of rapid Docker startup, I have made adjustments to two related scripts in the Docker startup process. First, I added a env `SKIP_CHECK_ULIMIT` to the `start_be.sh` script, which will skip the size checks for `swap`, `ulimit`, and `max_map_count`. At the same time, I used `--console` to start the process and print logs. The reason why I did not use the `--daemon` daemon command to execute is that starting with a foreground log printing method in a Docker container is the correct and reliable approach.

At the same time, I added a check logic for a `be.conf` configuration item in the `init_be.sh` script: if it is the first time starting, append the export `SKIP_CHECK_ULIMIT=true` to skip the `ulimit` value check in the BE process. In summary, these adjustments can meet the basic requirements for rapid Docker startup usage.
