MDEV-35304: Add Connects_Tried and Master_Retry_Count to SSS
When the IO thread (re)connect to a primary, no updates are available besides unique errors that cause the failure. These new `Master_info` numbers supplement SHOW SLAVE STATUS’s (most- recent) ‘Connecting’ state with statistics on (re)connect attempts: * `Connects_Tried`: how many retries have been attempted so far This was previously a local variable that only counted re-attempts; it’s now meaningful even after the “Connecting” state concludes. * `Master_Retry_Count` (from MDEV-25674): out of how many configured Side-note: Some of the tests updated by this commit dump the entire SHOW SLAVE STATUS, which might include non-deterministic entries.
