-- @brief Getter for host_stats values
-- Need this getter as there are certain host keys which contain dots, so
-- lua is unhappy and doesn't allow us to use the dot-notation to access table keys.
-- For example host_stats["tcpPacketStats.sent"]["retransmissions"] has "tcpPacketStats.sent" which
-- contains a dot so we are unable to use the notation host_stats.tcpPacketStats.sent.retransmissions as
-- done for other keys. To access these keys, we need to use the [] notation inside a `key` function.
