This also amends a commit from Brock Whittaker <brock@zulipchat.com>
that merges two separate functions for YouTube videos and Vimeo videos
into a generic video recall function.
Fixes#7550.
We add two functions:
1.) check_schedule_message(): This function is responsible for
doing the essential initial checkes to verify the validity of
the message. These checkes include things like if user is
allowed to send messages to some stream or not or if the user is
a super_user. All this is basically done by further calling
check_message() with appropriate parameters. This is on the same
lines as is check_send_message().
2.) do_schedule_messages(): This function is responsible for
creating ScheduleMessage table rows for a list of messages that
are to be scheduled. This basically accumulates the ScheduleMessage
objects in a list and then bulk creates the rows.
This adds UI fields in the bot settings for specifying
configuration values like API keys for a bot. The names
and placeholder values for each bot's config fields are
fetched from the bot's <bot>.conf template file in the
zulip_bots package. This also adds giphy and followup
as embedded bots.
This endpoint is about to become an API-style route and have the legacy
decorator removed from its view. Other endpoints will be used in tests
instead of it.
* For strikethrough formatting: Slack's '~strike~' to Zulip's '~~strike~~'.
* For bold formatting: Slack's '*bold*' to Zulip's '**bold**'.
* For italic formatting: Slack's '_italic_' to Zulip's '*italic*'.
* For mentioning formatting: Slack's <@slack_id|short_name> to Zulip's @**full_name**.

load_bot_config_template(bot) parses the <bot>.conf
template file, which can be found in the zulip_bots
package for each bot. It then returns the INI content
of that file as a dict.
Currently the zip file is extracted to the root of
zulip directory no matter where the the zip file.
The extracted data is not useful after running the command
which pollutes the zulip directory. It make more sense to
extract it to the same directory of zip file especially
when the zip file gets downloaded to /temp like in the tests.
