TCP connection pool have a mode where unassigned connections are closed (for TCP proxy) #4409
Description
Envoy version used are
envoy version: d2fa5f3b4c1f09a8e6fa96ecc8f64555d67a85f6/1.8.0-dev/Clean/RELEASEenvoy version: d2fa5f3b4c1f09a8e6fa96ecc8f64555d67a85f6/1.8.0-dev/Clean/RELEASE
Bug Template
We have noticed that Envoy doesn't always reuse connections from the connection pool and sometimes will open new connections unnecessarily.
Description
We discussed this bug in slack where we were asked to open a github issue.
Repro steps:
Use the following config and have a dummy process listening on port 8080 then run nc -vz localhost 61001 repeatedly. The repro steps are very similar to those in #4310
