This commit adds a `*time.Location` instance in both `frontend.Session` and `process.SessionInfo`, to store session level timezone info. We can use `set time_zone=XXX` to modify it. Three different formats are supported, the same as MySQL:

* set time_zone="SYSTEM". It sets timezone to your operating system's value, which is the default.
* set time_zone="+01:00". The timezone string specifies offset to UTC. It comprises a not omittable "+/-" sign, 2-digit hour, a ":" sign, and 2-digit minute. Legal values are between -13:59 and +14:00.
* set time_zone="America/New_York". The timezone string is a legal IANA TZ database name.

TIMESTAMP values are converted from the current time zone to UTC for storage, and back from UTC to the current time zone for retrieval. (This does not occur for other types such as DATETIME.)

mo has its own error code/message, and need to adapt mysql error code.
- define `moErrorMsgItem{errorCode, mysqlErrorCode, errorMsgOrFormat}` to handle `moErrorCode->mysqlErrorCode` mapping rules
- define `New(errorCoe, args)` and `NewWithContext(context.Context, errorCode, args)` to handle error reporting
- modify reference of `moerr.ErrTxnClosed` error, as an example of `moerr.New(...)`
- predefine `Group 6: sql error` as sql error, which normally can be converted to mysql error code.

In previous design, there is not context.Context going through the frontend and the computation engine.
In 0.6, the computation engine introduces the context.Context.
So, I add the context.Context in the frontend and try to connect context.Context with modules -- metric and trace.
I am not sure the usage of the conext.Context in these modules is right. So I propose the PR.

The hierarchy of the context.Context:
```
rootCtx(context.Background)
|
|
WithCancel()
|
|
\|/
cancelMoServerCtx
|
|
WithValue(configuration)
|
|
moServerCtx
|
|
----------------------------> context in metric, trace
|
|
\|/
cancelRoutineCtx (every network connection has an independent context)
|
|
------> WithCancel----->AuthenticateCtx (login authentication -- user, password, role)
|
|
cancelRequestCtx (every request from the client has a new context)
|
|
-------> WithCancel ------> LoadBatchCtx ( every batch has a independent context)
```

Enabled TestGossipInSimulatedCluster to be always executed, it simulates a 48 nodes cluster to test gossip on log shard info. The test is slightly tweaked to check all nodes except one can get expected shard info in a timely manner.

Updated go.mod to use a private fork of memberlist for now as the upstream version has known data race issue.

* Remove tae types.

One type system for all.

Removed tae types.   Moved encoding into types to reduce a cyclic
dependencies.

Most the changes are like
find . -type f -exec sed -i 's/Type_BOOL/T_bool/g' {} \;

Some mock code in tae types are moved to container types. I don't think
those clock related actually belongs to types, but kept within types so
that the rest of the code refactoring is automatic.

* go fmt.
