TELCU-26 Closing connection when partial messages break parser

[genseric-ghiro]

Summary

• Currently, we hold a single connection per address. When a corrupted arrives, parser may break and doesn't recover for the rest of the connection's lifetime. We still read messages at the kernel level, but we don't process them, which makes existing requests hang and new requests unprocessable. This PR fixes this issue in the following way:
• if there's a partial message detected for a certain amount of time (10s default), close the connection, and reopen a new one
• if there's a partial message detected for a certain amount of bytes (65MB), close the connection, and reopen a new one
• allow multiple connections per address (improvement)
