Add support for Sematext Cloud Europe

[mduvanel]

Just a thought: as I am trying to switch between an EU-based login and a US-based login for comparison, I realise there is no documented way to explicitly end a session.
Would it make sense to add a logout option of some sort? Could be done in a separate issue though.

[mduvanel]

After playing around with a first implementation, I have the feeling that a property that can be set is not the best way to handle the region.

With this model, one has to start by setting the region using logsene-cli config set --region EU. Since the user is not logged in yet, he will have to login first in order for the command to execute properly. However login will fail because user cannot login using his EU login, since the config is not set yet... This is a chicken-and-egg problem.

Also, changing the region after you are logged in does not really make sense, because a login is valid for a region and not necessarily the other. At best, setting the region would have to force a logout.

To me it feels that the region is closely tied to the login action, and it would make more sense to ask for the region even before the username and password. Something like this:

$> logsene-cli search -q ERROR
No active sessions. Please log in using your Sematext account:
Enter your region (default is US): EU
Enter your username: [email protected]
Enter your password:
Successfuly logged in and retrieved API key.
...

Once the region is set it should be saved for the session, because all subsequent requests should be using the same region-specific URI. So it would make sense to keep track of the regionproperty like it is done for username, but not expose it through the config API.

Do you agree with this proposal?

Any news on this issue?
If possible I would gladly try to contribute for it as I am quite interested in using a CLI tool for SemaText.

A PR would be great, @mduvanel !

@mduvanel If you're interested, there's a branch region that I pushed yesterday.
master needs to be merged into it (locally, of course) and then tested.
The public API changed in the meantime and those changes are also in the region branch.
Here's the API spec, just in case you need it: https://apps.sematext.com/api-explorer
Ask if you need help

[mduvanel]

@mbonaci Thank you, I will pull this branch and work from there.
I was confused yesterday because I could not get even plain curl authentication requests to work with API v2 as mentioned in this ticket to work, but I will have a look at the API explorer to understand what I am doing wrong - and use v3 now.

I initially thought I'd let users keep both sessions alive (with region-apiKey stored in config) at the same time and allow "switching" between them without the need to logout/login, but that may end up being too complicated and likely confusing.
So yes, I agree with your proposal.

BTW @mduvanel, the logout command is a great suggestion, now that there's a need to switch between regions.
I'm opening a separate issue for that - #11.
I bumped the version to v2.3.0 and published it to npm.
