[Enhancement](action) Support request the table schema of Non-OLAP table through http action

[weizuo93]

Proposed changes

Issue Number: close #14517

Problem summary

This action is used to obtain the table structure information of the specified table.

curl -X GET -u xxx:xxx http://fe_host:http_port/api/{db}/{table}/_schema

But for Non-OLAP table, this action can not work such as view. For example:

{"msg":"Error","code":1,"data":"errCode = 7, detailMessage = table type is not OLAP, tableName=xxx, type=VIEW","count":0}

This patch is to support request the table schema of Non-OLAP table through this action.

Can we use db.getTableOrMetaException(tblName)?

@stalary Thanks for your comment. This patch is to support querying doris view through spark, but there are some problems. I will close this PR.
