Add mTLS capability for Otelcol receiver/exporter communication #184
Description
Enhancement Proposal
As part of an initial investigation I created this PR:
It attempts to setup the otelcollector-config for mTLS communication. This is not fully thought out, as it relies on the root store rather than providing a client_ca_file per communication channel in the server TLS config.
TLS already works without this feature, but would allow otelcol to trust the clients it is communicating with via mTLS.
