# What this PR does
Remove
[`apps.get_model`](https://docs.djangoproject.com/en/3.2/ref/applications/#django.apps.apps.get_model)
invocations and use inline `import` statements in places where models
are imported within functions/methods to avoid circular imports.
I believe `import` statements are more appropriate for most use cases as
they allow for better static code analysis & formatting, and solve the
issue of circular imports without being unnecessarily dynamic as
`apps.get_model`. With `import` statements, it's possible to:
- Jump to model definitions in most IDEs
- Automatically sort inline imports with `isort`
- Find import errors faster/easier (most IDEs highlight broken imports)
- Have more consistency across regular & inline imports when importing
models
This PR also adds a flake8 rule to ban imports of `django.apps.apps`, so
it's harder to use `apps.get_model` by mistake (it's possible to ignore
this rule by using `# noqa: I251`). The rule is not enforced on
directories with migration files, because `apps.get_model` is often used
to get a historical state of a model, which is useful when writing
migrations ([see this SO answer for more
details](https://stackoverflow.com/a/37769213)). So `apps.get_model` is
considered OK in migrations (even necessary in some cases).

# What this PR does
This PR does three improvements in twilio_phone_provider:
1.
[Speed-up](https://github.com/grafana/oncall/pull/2034/files#diff-7a311767169c024e60e2b4e35fd531dd6e2f1ea785cfc84263e11e7932d622af)
query which calculates amount of phone_calls/sms left.
2. Remove code which was needed only for backward compatibility during
the release of PhoneProvider refactoring and improves logging for
handling status/gather updates.
3. Add db_index to twilio_sid. We are doing lot of lookups by sid and
with increasing amount of data it became resource consuming.

# What this PR does
This PR moves phone notification logic into separate object PhoneBackend
and introduces PhoneProvider interface to hide actual implementation of
external phone services provider. It should allow add new phone
providers just by implementing one class (See SimplePhoneProvider for
example).
# Why
[Asterisk PR](https://github.com/grafana/oncall/pull/1282) showed that
our phone notification system is not flexible. However this is one of
the most frequent community questions - how to add "X" phone provider.
Also, this refactoring move us one step closer to unifying all
notification backends, since with PhoneBackend all phone notification
logic is collected in one place and independent from concrete
realisation.
# Highligts
1. PhoneBackend object - contains all phone notifications business
logic.
2. PhoneProvider - interface to external phone services provider.
3. TwilioPhoneProvider and SimplePhoneProvider - two examples of
PhoneProvider implementation.
4. PhoneCallRecord and SMSRecord models. I introduced these models to
keep phone notification limits logic decoupled from external providers.
Existing TwilioPhoneCall and TwilioSMS objects will be migrated to the
new table to not to reset limits counter. To be able to receive status
callbacks and gather from Twilio TwilioPhoneCall and TwilioSMS still
exists, but they are linked to PhoneCallRecord and SMSRecord via fk, to
not to leat twilio logic into core code.
