provide system token authentication
We run a couple of scripts that access the Mattermost API, e.g. a script that posts a message to all Town Squares in all teams on our server and a script that creates user accounts (as we allow email login but disable email account creation so that we can control who creates accounts on the server). Right now we have the personal auth token of an administrator hardcoded in the scripts, but obviously this is suboptimal in case the administrator leaves the company, and messages appear to be sent from said administrator.
Therefore it would be great if administrators could create a "system" auth token for certain kinds of integrations that is decoupled from personal accounts.
