Bug #78897 documentation correction for --connect-retries and --connect-retry-delay

Description:
The documentation descriptions for --connect-retries and --connect-retry-delay are not entirely correct.

They need to be fixed in the links below:

1) https://dev.mysql.com/doc/refman/5.6/en/mysql-cluster-program-options-common.html
description change required: "attempt" to "reattempt"
--connect-retries=0 does not mean no attempts at all. There are no 'reattempts', i.e a single attempt is always made;
--connect-retry-delay=0 does not mean wait forever. It means there is no delay between the retries.

2) https://dev.mysql.com/doc/refman/5.6/en/mysql-cluster-program-options-common.html#option_n... 
(description change & spelling error: "befpore" needs to be changed to "before")

3) https://dev.mysql.com/doc/refman/5.6/en/mysql-cluster-program-options-common.html#option_n... 
(description change & spelling error: "befpore" needs to be changed to "before")

How to repeat:
ndb_config --connect-string=no_such_host --connect-retry-delay=0
ndb_config --connect-string=no_such_host --connect-retries=0

Suggested fix:
--connect-retries : Set the number of times to reattempt a connection before giving up. 0 means a single attempt.
--connect-retry-delay :Set the number of seconds to wait per attempt to make a connection before giving up. 0 means no delay between retries.

Thank you for your bug report. This issue has been addressed in the documentation. The updated documentation will appear on our website shortly.
