Upgrade to monolog v2

[d8vjork]

Summary

• As described in PHP 7.4 support (upgrade monolog, dependencies) #191, just bringing compatibility with Laravel 6.x & 7.x

I'm creating a new project from scratch, at least, I need to make it work.

Test plan

Fresh Laravel project just including the SDK (no wrappers/implementations yet), it failed with dependency conflicts.

All tests passed after monolog upgrade.

Issues

• Sorry, it doesn't finish the issue mentioned before, it just solve the monolog part (but still some work upgrading PHPUnit dependency + tests to make it work on PHP 7.4), anyway Laravel 7 still require PHP 7.2 / 7.3, so not a major issue yet.

Also lots of unsupported PHP versions: 5.5, 5.6, 7.0 and 7.1 are out of support, 7.2 is the only way to go with this monolog upgrade

@d8vjork we will have to take a much closer look at this, but in its current form we cannot take this change since this means dropping support for some PHP versions.

We are taking a closer look at our end on how we can introduce PHP 7.4 support and support Laravel 6 and 7.

[d8vjork]

Maybe a different branch/major version could be an option.

Thanks for the reply anyway

Do we have any progress in relation to the version of the "monolog" for version "2"?

[ravanscafi]

Could we please prioritize this? It could be tagged as v4.0 or whatever is best.
This is preventing us from update our project.

Feel free to use okdewit/optimizely-php-sdk v4.0.3 as a stopgap solution. It's a packagist-published fork which is regularly synced from the main branch of this repo.

I will mark my fork as deprecated when this has a tag that supports Monolog v2 and Guzzle v7.
