chore: increase transformer request timeouts

[atzoum]

Description

There are multiple occasions where we currently need a much higher timeout than 30s during transformation requests, e.g. when using large event batches and transformer needs to perform some external request(s). This has also caused a number of issues already, forcing us to manually increase this timeout. Therefore increasing the default timeout to 10 minutes, instead of 30 seconds.
