wtdb+wtclient: segregate session-key-index reservations by blob-type
This commit introduces a change in the key format used to reserve/lookup
session-key-indexes. Currently the reservations are stored under the
tower id, however this creates issues when multiple clients are using
the same database since only one reservation is permitted per tower.

We fix this by appending the blob type to the session-key-index locator.
This allows multiple clients to reserve keys for the same tower, but
still limits each client to one outstanding reservation. The changes are
made in a way such that we fall back to the legacy format if the a
reservation under the new format is not found, but only if the blob type
matches blob.TypeAltruistCommit, which is so far the only actively
deployed blob type.

wtclient: add backoff in negotiation when createSession() fails
Currently if the tower hangs up during session negotiation there is no
backoff applied. We add backoff here to avoid excessive CPU/network
utilization during unexpected failures.

watchtower/wtclient: only reset iterator once we've exhausted all candidates
Doing so allows us to load balance sessions better amongst all of the
tower candidates.

watchtower/wtdb: create embedded ClientSessionBody
This commit splits out the portions of the ClientSession into an
embedded ClientSessionBody, since these fields will be serialized
together on-disk.
