Sync ingestion: manage error on file issue and allow ingestion of elements with missing files

[aHenryJard]

Description

When there is a missing file or a file that is not allowed to user for any reason (usually an HTTP 503 in logs), ingestion in sync manager of data is stopped.
Would be great to try/catch the error on file get and ingest element data.

Need to discuss if we log a warning or error in case of missed files.

Implementation that requires a try/catch is around here:

opencti/opencti-platform/opencti-graphql/src/manager/syncManager.js

Line 90 in 101d70d

const response = await httpClient.get(`${httpBase(uri)}${fileUri.substring(fileUri.indexOf('storage/get'))}`);

Environment

1. OS (where OpenCTI server runs): { e.g. Mac OS 10, Windows 10, Ubuntu 16.4, etc. }
2. OpenCTI version: { e.g. OpenCTI 1.0.2 }
3. OpenCTI client: { e.g. frontend or python }
4. Other environment details:

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. { e.g. Run ... }
2. { e.g. Click ... }
3. { e.g. Error ... }
