Set up POTel patching

[sentrivana]

Problem Statement

We need to kick off OTel's autoinstrumentation someplace.

Solution Brainstorm

Use OTel’s discovery of entry points but have a tailored list of integrations that will be excluded and instead will be turned on manually (so that we can enable extra options etc.).
