* epoch: misc fixes and logging * blob: misc helpers * cli: removed useless 'repository upgrade', replaced by 'repository set-parameters' * content: implemented indexBlobManagerV1 which uses epoch manager * cli: commands to manipulate repository epoch parameters * cli: commands to examine epoch-based indexes * content: added test suite that uses epoch-based index manager * content: fixed a ton of test data races caused by sharing blobtesting.DataMap * cli: additional tests and validation for 'repository set-params' * testing: replaced the use of suite with our own, since suite is not parallelizable
