This is basically implementation of the https://github.com/grafana/grafana/issues/8900#issuecomment-435437167
points, except for the type conversion bit.

I tried to implement idea mentioned in cockroachdb ticket (see below).
And it is possible, but it complicates things as lot - not only we have to
have 4 SQL statements instead of one, but we would have to copy the column
structure as well - PK, FG, indexes and stuff, plus there will
be additional downtime with this approach.

So idea for this pull is to prepare our SQL as much as possible, so when
cockroachdb will add support for full type conversions, we could easilly add
support for it as well.

* Add `CASCADE` to `DROP INDEX` statement

* Make string conversions explicit

Thanks @Luit

Alerting: Adjust label for send on all alerts to default 

Initial alpha datasource that saves data directly in a panel or in the shared datasource configs.

Temporarily expose getBackendSrv while we figure out a long term solution.  This will unblock developing some more complex react external plugins.

For react panels the scopedVars did not contain the built in __interval and __interval_ms
variables.
