Bump monolog to v2 or v3

[williamdes]

Hi @sgiehl

On Debian I upgraded Monlog to v2 and then v3
See (v2): https://sources.debian.org/src/matomo/5.2.2%2Bdfsg-1/debian/patches/0006-Upgrade-monolog-to-v2.patch/
See (v3): https://sources.debian.org/src/matomo/5.2.2%2Bdfsg-1/debian/patches/0028-Upgrade-monolog-to-v3.patch/

I think I will do a PR for v2 since it is PHP 7.2 compatible: https://github.com/Seldaek/monolog/blob/2.x/composer.json#L16

Hey @williamdes,

It might be better not to patch any library updates into releases, as that can always break compatibility with various plugins.
Monolog2 seems to have a couple of breaking changes, which require changes within Matomo itself.
We most likely shouldn't do that outside of a major release, to ensure all plugins remain compatible.

Okay, for Debian it works differently so I do kit have the choice. But for normal distribution I totally understand.
When do you plan to open a branch for the next major version?
Should i close this issue?

[sgiehl]

We will most likely do a major somewhen this year, but it hasn't been planned yet. But updating all dependencies to newer versions will be a part of it anyway, so I'll close this issue for now.
Thanks nevertheless for your approach!

Okay, please ping me or check out the patches folder on Debian as the work is maybe already done and can be imported
