Slack triggers start agent sessions from a channel

Add Runtime's Slack app to a workspace with runtime agents slack install (or POST /v1/agents/slack/installs; the link works only for a signed-in member of the account), invite it to a channel, and add a slack trigger with the workspace's team and the channel's id. Each new message in the channel starts a session; a reply in its thread joins that session. The session's replies and result are posted in the thread, its status is one message edited in place, and each ask is posted with a button for each option. GET /v1/agents/slack/teams lists the added workspaces and DELETE /v1/agents/slack/teams/{team} removes one. Available in the JavaScript, Python, Go, Java and Ruby SDKs (agents.slack).
