Amm info handler new

[arihantkothari]

• Adds amm_info handler to clio

The amm_info can be fetch by "amm_account" field. But I did not see the implementation of it. Is it in the PR's scope? https://xrpl.org/amm_info.html#amm_info Since it is already in the document, I think we need to implement it .

I implemented this in my last commit, thanks for looking into it carefully.

we need to check :
1 ammAccount and issue1/2 can not be set at the same time
2 ammAccount or issue1/2 must be set

[cindyyan317]

do we need to check the existence of ammAccountID which is from the amm ledger object 🤔

[cindyyan317]

I understand the ammAssetValidator is from ledger_entry . You may need to bespoke the error code here.

[arihantkothari]

I removed the ammAssetValidator from ledger_entry and added it to validators. What do you mean by "bespoke the error code" ?

[cindyyan317]

Try to input invalid asset , you will see rippled raises different error for the ledger_entry and amm_info.

I have pushed the amm_info unit tests but they are really incomplete. This is the only thing that is incomplete in the PR.
