Allow custom email notifications

[shenne-ls]

So far, BioMAJ email notication consists of a simple mail looking like this:

From:   Author <biomaj@biomaj.com>
Sent:   lundi 9 mars 2020 01:27
To: John Doe
Subject:    BANK[entrezgene] - STATUS[True] - UPDATE[True] - REMOVE[True] - RELEASE[2020-3-8]

2020-03-09 00:10:06,696 INFO  [root][MainThread] Log file:

It would be nice to be able to customize those emails in various ways:

• Changing "Author" sender to whatever we want
• Make mail subject more understandable for someone not knowing BioMAJ. For example:
  • If UPDATE[True] & STATUS[False] --> [BioMAJ] Update failed for bank XXX – Version YYY
  • If UPDATE[True] & STATUS[True] --> [BioMAJ] Bank XXX – Version YYY updated successfully
• Having the full log as attachment and only the relevant part in the mail body.
• Being able to send this email to different users according to the bank configuration (Maybe already feasible ?)
• Customizing email look-and feel with help of a templating solution.

This would make this email much more valuable for an end-user target audience.

regarding mail destination, it is possible to send to different users, per bank via config param mail.admin , with a comma separated list

in global.properties you can set:

mail.admin=admin@you

in a specific bank property set you can override:

mail.admin=admin@you,someoneelse@somewhere

Regarding the from, it is taken from config mail.from (customizable per bank if needed)

Author changed to BioMAJ for using jinja2 templates for header/body of message and options to include tail of log_file and/or attach log file to mail, see smtp options in docs/global.advanced.properties
