fix: [cron] make cron build again
fix: [cron] make cron build again
This involves a deep upgrade. Changing base distribution from debian
towards alpine, and changing the way the schedule-command relation is
handled. Consequences:
- size of image went from 195MB to 45MB
- build process simplified (only one small ``Dockerfile``)
- dependencies are not in the charm anymore but fetched on build
from our download server
- local cron business intelligence was moved in the cron charm
- extreme simplification for implementing run-once charms relation with
cron.
- some simplification for charms that adds some intelligence on their
side.

* Usage |
|||
|
|||
By adding =cron= as a service, all other services in auto pair mode, |
|||
requiring a =schedule-command= will use it. |
|||
|
|||
#+begin_src yaml |
|||
cron: |
|||
#+end_src |
|||
|
|||
There are no options to set. |
|||
|
|||
** =schedule-command= relation |
|||
|
|||
If most other services will have default options and set these values |
|||
automatically. You probably don't need to configure anything in the |
|||
relation's options if defaults suits you. |
