[META] Release v1.4

[msm-code]

Ok, let's focus on the next release. Initial set of issues I think are good candidates for the next version:

Make it easier to deploy multi-agent, multi-server, large-scale cloud deployment for orgs that can spare the money:

• [x] #296
• [ ] #300

And also make it easier to deploy single-agent, single-server, small scale bare-metal deployment without paying a lot (for me):

• [x] #297 (and also #243)
• [x] #302

And fix bugs related to that efforts:

• [x] #301
• [x] #299
• [x] #303
• [ ] #257
