Fix es-archive namespace default values

[albertteoh]

Signed-off-by: albertteoh albert.teoh@logz.io

Which problem is this PR solving?

• Fixes Fix archive default values reported for ES and Cassandra #2853

Short description of the changes

• Sets the default config of "other" namespaces to the primary's default config.

• As discussed in Fix archive default values reported for ES and Cassandra #2853, the primary default of 72h is misleading to users because an archive fetch should have no "lookback" limit, fetching any traceID that is in archive storage.

  This PR also removes the --es-archive.max-span-age flag to avoid confusing users.

Testing

• Confirmed --es-archive.max-span-age no longer appears in --help for both query and collector.
• Confirmed archive defaults are correctly based on primary config defaults for both query and collector. E.g.:

      --es-archive.max-doc-count int                       The maximum document count to return from an Elasticsearch query. This will also apply to aggregations. (default 10000)

the ES integration tests don't seem to like this change

[albertteoh]

This should fix both the failing ES integration tests and Crossdock builds.

The cause was due to archive mode being enabled by default and attempting to either ping a non-existent ES for a version (failing ES integration test) or attempting to communicate with ES on the wrong (default) IP address (failing Crossdock builds).

The original behaviour was to have archive mode disabled.
