We already have a MS Teams integration but MS Teams is discontinuing
the incoming webhook feature used by this integration:
https://devblogs.microsoft.com/microsoft365dev/retirement-of-office-365-connectors-within-microsoft-teams/
MS Teams now recommends to use Workflows to post messages
via webhook. MS Teams does not provide backwards compatibility or
an upgrade path for existing integrations.
This commit adds a new "msteamsw" integration which uses MS Teams
Workflows to post notifications. It also updates the instructions
and illustrations in the "Add MS Teams Integration" page.

urrlib3's default number of retries is 3.
If requests to the S3 API are timing out, the retries usually
don't help, but a 10-second timeout turns into 10*3=30 seconds
of python code being blocked.
Defer loading body_raw, instead load its first 150 bytes
as "body_raw_preview". This reduces both network I/O to database,
and disk I/O on the database host if the database contains large
request bodies.

We used "body" to store request body as text.
In 2022 we added "body_raw" and started to use it to store request
body as bytes.
In python code we currently need to inspect both fields,
because the data could be in "body" (for old pings) or in
"body_raw" (for newer pings). My plan is to eventually get rid
of the "body" field, and have "body_raw" only. This data migration
is a step towards that: for any Ping objects that have non-empty
"body" field, it moves the data to the "body_raw" field. After
applying this migration, the "body" field should be empty (empty
string or null) for all Ping objects.
Instead, make it set a local `have_apprise` variable, and use
it in the hc.api.transports.Apprise class.
If hc.api.transports sets APPRISE_ENABLED to False,
then the apprise system check in hc.api.apps will not see the
original value and therefore will not run.
* fix: show warning if apprise is enabled and not installed in environment
* renamed appraise check register
* revert back changes in transport for apprise
There are three related changes:
* Removed legacy timezones from hc.lib.tz.all_timezones
* Added data migration to update existing Check.tz values
* For backwards compatibility, added code to automatically
replace a legacy timezone with a canonical timezone when a
legacy timezone is passed to an API call
I used the timezone mapping on
https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
This is primarily to make notification lookups by code efficient.
We look up notifications by code in hc.api.views.boundces.
This field has a default value (uuid.uuid4), so any null values
will be filled with random UUIDs during migration.
The "senddeletionscheduled" management command creates dummy
Flip objects, but does not save them to the database.
Some transport classes expect the flip object to have a non-null
"created" field. Normally it gets set when saving the flip object
to the database, here we need to do that manually.
