We already handle one type of exception for too many columns case with message like: ```Too many columns (10067) in schema. Only 10000 columns are allowed``` It turns out BQ can fail with different one in this case, like: ```Too many total leaf fields: 10001, max allowed field count: 10000``` so we have to handle it as well.
After the loader alters the table to add new columns, it immediately opens a new Writer and expects the Writer to be aware of the new columns. However, we have found the Writer might get opened with no awareness of the newly added columns. Presumbably because of the async nature of BigQuery's architecture. This fix works by retrying opening the writer until eventually it should get opened with awareness of the new columns
When schema evolves, e.g. when new nested field is added to entity, loader should explicity try to alter underlying BigQuery schema. It works correctly for self-describing events (unstruct columns), but as it turns in case of contexts it doesn't modify schema, alter is skipped, what results in bad data. This commit should fix this problem.
