Support for psr/log version 3

[manalan-km]

Hi all, Our organisation uses psr/log and monolog/monolog packages along with elastic/apm-agent for our application. While updating psr/log, we ran into the issue of incompatibility with version 1 of elastic/apm-agent with v3 of psr/log and monolog/monolog. Just wondering if there will be a support in the near future for the elastic/apm-agent with v3 of the mentioned packages/? Thanks :)
