This PR does a bunch of changes to prepare OnCall for Unified Slack App:
1. Install Slack via Chatops-Proxy. This change contains two parts:
getting a Slack install link from chatops-proxy
([code](https://github.com/grafana/oncall/pull/4232/files#diff-437a77d49fc04b92d315651b3df5991000b1ab74cf60aabb21aa77cb2823bf52R46))
and receiving a "slack installed" event from chatops-proxy
([code](https://github.com/grafana/oncall/pull/4232/files#diff-976d106f0962be5c1de5e35582193f68435ed0c17f2defd6bd2857bf6e27f65d)).
Also it means that OnCall doesn't need to register slack_links anymore
when slack is connected/disconnected. These changes are behind
UNIFIED_SLACK_APP_ENABLED flag and should be no-op if flag is not
enabled.
2. Get rid of Multiregionatily restrictions - instrument all slack
interactions with a ProxyMeta - json data telling chatops-proxy where to
route the interaction. Note, that it doesn't apply for "Add to
resolution notes" message action - it will be handled differently in
following PR.
3. Move all chatops-proxy related stuff from common/oncall-gateway to
apps/chatops-proxy
Minor changes:
1. Remove usage of **CHATOPS_V3** flag. Chatops v3 is already released
(It's a refactoring from previous quarter)

This PR makes OnCall compatible with chatops-proxy v3. When CHATOPS_V3
is enabled, oncall will use new api client to register tenants and slack
installations. Also I added v3 routes for slack and telegram, so it's
possible to test new chatops proxy.
Currently two versions of chatops-proxy api are deployed, but they are
not compatible. They are doing same thing, using different db model and
tables. Once only v3 version will be left in prod, I'll remove
CHATOPS_V3 env var, all leftovers of previous api client and v3 slack
and telegram routes.
