improve regexp for CLF-like parsing

[landryb]

in my testing, if using a raw string with an r prefix and double quotes here, it wasn't extrapolated by the python code and used as a string started by r.... so don't use the r prefix and use single quotes instead, matches the actual lines produced by the s-p and the gateway.

while here, OPTIONS is the right HTTP method name, not OPTION

i haven't tested/modified the regex string for the opentelemetry parser but maybe it has the same issue.

sidenote: i dunno which file should be used between analytics-cli/config/analytics_cli.yaml and analytics-cli/src/georchestra_analytics_cli/config/analytics_cli.yaml, the first one has less comments and seem to predate the second one.

Thanks @landryb. Actually this regex strings issue reminds me of something. I don't really understand why in some cases the r prefix is counter-productive. I'll have to investigate this.

Good catch for the OPTION(S) issue.

About the config files, maybe I'll have to add some doc about this:

• analytics-cli/src/georchestra_analytics_cli/config/analytics_cli.yaml provides the default values. It is thought to serve as a reference of what the config files supports
• analytics-cli/config/analytics_cli.yaml is a sample config file you can call to override the default ones. Maybe I should remove it completely from the repo
