Start a heal sequence that scans data under given (possible empty)
`bucket` and `prefix`. The `recursive` bool turns on recursive
traversal under the given path. `dryRun` does not mutate on-disk data,
but performs data validation. `incomplete` enables healing of
multipart uploads that are in progress. `removeBadFiles` removes
unrecoverable files. `statisticsOnly` turns off detailed
heal-operations reporting in the status call.
but performs data validation.
Two heal sequences on overlapping paths may not be initiated.
The progress of a heal should be followed using the `HealStatus`
The progress of a heal should be followed using the same API `Heal`
by providing the `clientToken` previously obtained from a `Heal`
API. The server accumulates results of the heal traversal and waits
for the client to receive and acknowledge them using the status
API. When the statistics-only option is set, the server only maintains
aggregates statistics - in this case, no acknowledgement of results is
required.
