Router adds name mapping scripts

[zzl221000]

Motivations

Filters can use wildcards, but the specific tables being synchronized are variable, which can cause the table mapping feature to become ineffective.

• Would you like to implement this feature? [N]

Solution

I think the best way is to use embedded scripts to handle mapping relationships, which is more flexible.

I think db_map, tb_map，col_map , and even "etl by lua" can solve this issue ?

please refer to: https://github.com/apecloud/ape-dts/blob/main/docs/en/config.md#router
and : https://github.com/apecloud/ape-dts/blob/main/docs/en/tutorial/etl_by_lua.md

Does the tb_map function support pre_(.+): $1?
All tables need to have prefixes or suffixes removed.

It seems that Lua can solve this problem.

Edit: etl by lua does not seem to support mongodb

OK，I got your point, we will consider this after the Chinese new year.
