RUMM-3011: Raise upload limit to 100MB for US1 datacenter

[0xnm]

What does this PR do?

This change raises upload limit for US1 datacenter only to 100 MB (and bumps timeout to 60s for all DCs). This is temporary change, because once all DCs are able to support large uploads, this limits will be aligned.
