docs: add nginx access log analysis example

[ayewo]

PR checklist:

• Did you run ClangFormat ? N/A
• Did you separate headers to a different section in existing community code base ? N/A
• Did you surround proton: starts/ends for new code in existing community code base ? N/A

Hi again @jovezhong,

I've added another article to the examples. Hope you'll take a look 😉 .

[jovezhong]

Nice! I will check it soon. ETA: end of this week, if not sooner.

Hi @ayewo , this is certainly in the right direction. This is my first batch of the comments. Look forwards to more examples of how to use Timeplus Proton to understand the blog visit pattern in the past, troubleshotting/tuning, and even understand what's going on right now.

@jovezhong
Added significantly more content, along with some code.

This is ready for review.

Great work, thanks for putting things together. I left some comments. One nice to have thing is to use Grafana proton datasource plugin to visualize the SQL result, or use metabase plugin. But optional for sure.

I struggled with getting a column in the access log to be parsed correctly as a datetime64. I wanted to parse the below into 2024-04-24 15:49:59:

SELECT parseDateTime('24/Apr/2024:15:49:59 +0000', '%d/%b/%Y:%H:%i:%s %z');

Works fine on ClickHouse: https://play.clickhouse.com/play?user=play#U0VMRUNUIHBhcnNlRGF0ZVRpbWUoJzI0L0Fwci8yMDI0OjE1OjQ5OjU5ICswMDAwJywgJyVkLyViLyVZOiVIOiVpOiVzICV6Jyk7Cgo=

It seems Proton doesn't yet support theparse_date_time() function?

Hi @ayewo , regarding parsing '24/Apr/2024:15:49:59 +0000', can you create a new GitHub issue or discussion? We will implement it soon.
