Feature request: Include more detail in failed task email/telegram notifications

[Altersoundwork]

Hello,

Firstly, I want to take the time to thank the developers for Semaphore, it's been great to me and it helps immensely.

I run just under a hundred different tasks per day in many hosts from the semaphore server. A lot of times, the target host is off (error: "UNREACHABLE") which is perfectly fine (it'll try again tomorrow and so on). Of course this will set the task as FAILED and send a mail notification and telegram notification (I have both configured).

The problem is that both types of notification just have the following info:

Mail:

Subject: Task 'task_name_here' failed
Body:

Task XXXX with template 'task_name_here' has failed!
Task Log: LINK

Telegram:

Bot name
task_name
#XXXXX X ERROR - by user
LINK

Which in turn makes it impossible to see if it's just an "UNREACHABLE" failure or an actual (in my mind, real) failure.

So the request would be to add more content in the mail or notification, either the log itself or something that identifies the type of failure. Or if we want to get real fancy, add a fourth state to the tasks (other than "Success" "Failed" and "Stopped", something like "Unreachable")

This would allow to quickly browse through failures and get to the important ones.

Thank you in advanced for any consideration given to this!
