Refactor tap module to achieve synchronously closing other protocol dissectors upon identification (#1026)

Browse Source 
* Remove `tcpStreamWrapper` struct

* Refactor `tap` module and move some of the code to `tap/api` module

* Move `TrafficFilteringOptions` struct to `shared` module

* Change the `Dissect` method signature to have `*TcpReader` as an argument

* Add `CloseOtherProtocolDissectors` method and use it to synchronously close the other protocol dissectors

* Run `go mod tidy` in `cli` module

* Rename `SuperIdentifier` struct to `ProtoIdentifier`

* Remove `SuperTimer` struct

* Bring back `CloseTimedoutTcpStreamChannels` method

* Run `go mod tidy` everywhere

* Remove `GOGC` environment variable from tapper

* Fix the tests

* Bring back `debug.FreeOSMemory()` call

* Make `CloseOtherProtocolDissectors` method mutexed

* Revert "Remove `GOGC` environment variable from tapper"

This reverts commit cfc2484bbb.

* Bring back the removed `checksum`, `nooptcheck` and `ignorefsmerr` flags

* Define a bunch of interfaces and don't export any new structs from `tap/api`

* Keep the interfaces in `tap/api` but move the structs to `tap/tcp`

* Fix the unit tests by depending on `github.com/up9inc/mizu/tap`

* Use the modified `tlsEmitter`

* Define `TlsChunk` interface and make `tlsReader` implement `TcpReader`

* Remove unused fields in `tlsReader`

* Define `ReassemblyStream` interface and separate `gopacket` specififc fields to `tcpReassemblyStream` struct

Such that make `tap/api` don't depend on `gopacket`

* Remove the unused fields

* Make `tlsPoller` implement `TcpStream` interface and remove the call to `NewTcpStreamDummy` method

* Remove unused fields from `tlsPoller`

* Remove almost all of the setter methods in `TcpReader` and `TcpStream` interface and remove `TlsChunk` interface

* Revert "Revert "Remove `GOGC` environment variable from tapper""

This reverts commit ab2b9a803b.

* Revert "Bring back `debug.FreeOSMemory()` call"

This reverts commit 1cce863bbb.

* Remove excess comment

* Fix acceptance tests (`logger` module) #run_acceptance_tests

* Bring back `github.com/patrickmn/go-cache`

* Fix `NewTcpStream` method signature

* Put `tcpReader` and `tcpStream` mocks into protocol dissectors to remove `github.com/up9inc/mizu/tap` dependency

* Fix AMQP tests

* Revert 960ba644cd

* Revert `go.mod` and `go.sum` files in protocol dissectors

* Fix the comment position

* Revert `AppStatsInst` change

* Fix indent

* Fix CLI build

* Fix linter error

* Fix error msg

* Revert some of the changes in `chunk.go`
