[doc] improve MaxConcurrentRequests and MaxKeepBlobBuffers descriptions
The detail on how to calculate MaxKeepBlobBuffers was accidentally dropped in the 2.0 doc update.
The description for MaxConcurrentRequests erroneously states that it is only used by Keepstore.
The description for MaxConcurrentRequests states that the default (0) means no limit, but in the Keepstore code, 0 is translated to 2 * MaxKeepBlobBuffers.
documentation: update descriptions for MaxKeepBlobBuffers and MaxConcurrentRequests
keepstore: MaxConcurrentRequests set to zero should mean no limit
keepstore: warn if MaxConcurrentRequests is set to a nonzero value less
