Description:

Zoho is sunsetting v1 of their API tomorrow. This migrates to v2 of their API. It requires re-authorizing with them.

A portion of this code was provided by Korcomptenz.

Steps to test this PR:

1. Load up this PR
2. In Mautic, go to the Plugins page and click on Zoho
3. Copy the callback URL
4. In Zoho, register a new client https://www.zoho.com/crm/developer/docs/api/register-client.html to generate a client ID and secret. Use the callback URL copied from Mautic
5. After saving the client in Zoho, click the vertical ellipsis to the right of the new client and click Edit
6. Copy the Client ID to Mautic's Zoho config for "Application Client ID" and copy the Client Secret to "Application Client Secret"
7. Click the Authorize or Reauthorize button
8. A popup will open requiring you to login with your Zoho credentials then click Allow to authorize Mautic's integration
9. Map contact and/or company fields with priority facing Mautic
10. Enable all the features and select Leads, Contacts, and Accounts as objects to sync
11. Create a campaign with a "Push to Integration" action configured for Zoho and add contacts to the campaign
12. Execute the campaign and check that the Mautic contacts were created as Leads in Zoho
13. Now create a few new contacts in Mautic and different ones in Zoho as Leads and others as Contacts
14. Let the sync execute (run php app/console mautic:integration:synccontacts -i Zoho)
15. Check that the new contacts in Mautic were synced to Zoho as leads and that the Zoho Leads and Contacts were synced to Mautic
16. Edit the name of one of the contacts in Mautic and sync again. It should not have synced to Zoho
17. Edit one of the Leads or Contacts in Zoho and sync. The update should have synced to Mautic.
18. In Mautic, check the profiles of a contact that was created in Mautic and one that was pushed to Zoho. There should be an entry in the Integrations tab for Zoho with the Zoho ID.
19. Create an Account in Zoho and it should sync back to Mautic (the existing Zoho plugin does not currently support pushing companies from Mautic to Zoho and this PR does not implement it).

Working fine.
the config in Zoho seems to have change a bit though as I don't get the secret directly when I create the client.

use the menu when on the client ID page, and go in the Multi-DC page, here you can find the client secret.

We use it in production environment since date of the PR. I believe Acquia does the same, i'll mark it as ready to commit.
@alanhartless anything to do with Travis or we should ignore it ?

[alanhartless]

@npracht looks like the tests are failing because of maxmind. #8337 will need to be merged and PRs rebased on staging for tests to start passing again.

[dennisameling]

@alanhartless #8337 is merged now. Can you please go ahead and rebase your branch from staging? I don't have permissions for that 😄 thanks!

[alanhartless]

@dennisameling done, hopefully the tests will pass now

@alanhartless just one issue left in Travis:

1) MauticPlugin\MauticCrmBundle\Integration\ZohoIntegrationTest::testPopulateLeadData
'<Leads>\n<row no="">\n<FL val="...Leads>' does not match expected type "array".

[dennisameling]

Thanks for the quick fix @alanhartless and for providing this PR in the first place! I'm gonna go ahead and merge this one for the 2.16 release as @npracht mentioned they've been using it in production for a while already.
