Meteor 3 compatibility release

[StorytellerCZ]

Based on #59, this PR takes the next step and makes things compatible with Meteor 3.

TODOs left

• headless tests and CI fixed
• no version conflicts with Meteor >=3.0.1 && < 3.4
• no version conflicts with Meteor >= 3.4
• fix ddp queueing (see Meteor 3 compatibility release #60 (comment))

[StorytellerCZ]

I'm wondering if mtest is compatible with Meteor 3. I see no reason not to, but the cancellation is strange.

Looking forward to this! I tried getting the latest versions of both running with Meteor 3.0.2 but ran into this...

meteor add mizzao:user-status@2.0.0-beta.0
mizzao:user-status with version constraint 2.0.0-beta.0 has already been added.

wreiske@Wills-MacBook-Pro bluehive-ai % meteor add mizzao:timesync@1.0.0-beta.0
 => Errors while adding packages:             
                                              
While selecting package versions:
error: Conflict: Constraint mizzao:timesync@0.5.4 is not satisfied by mizzao:timesync 1.0.0-beta.0.

@wreiske I'll release a new rc for mizzao:user-status to fix this shortly.

After upgrading to Meteor 3.0.4 and to timesync 1.0.0 beta, the _timeSync method is called very often:

These are stats for 7 active containers on galaxy and about 700 connections

[StorytellerCZ]

That is a concern, but at first look I don't see any change that should cause an increase. 🤔

[alisnic]

@StorytellerCZ my take is that timesync does not account that ddp methods are queued, and if timeSync calls are blocked by other method calls it will just re-issue timeSync calls. I think this whole DDP thing needs to be reverted

[jankapunkt]

@StorytellerCZ this is blocking because mtest is not meteor 3 compatible

Anything those of us in the community can do to help? Just updated to Meteor 3.4 and unable to update this package.

Newer versions of the following indirect dependencies are available:
 * mizzao:timesync 0.5.5 (0.6.0 is available) 

[jankapunkt]

Hey @allenfuller I also found the update to 3.4 caused a lot of dependency issues. I think we need to bump core versions to include 3.4.

[jankapunkt]

I published a new version 1.0.0-beta.1 which you can try to install. I also noticed the issue @alisnic reported is not really resolved which is why I will assign myself to this PR to make this work and publish the package.
