New 'zos-jobs search jobs' command

[KevinLoesch1]

What It Does Adds a new zowe zos-jobs search job command. This allows the user to search a job or jobs spool files for a specified string or regular expression.

How to Test The command requires a job name, or wildcard, and either the --search-string or --search-regex parameter. For example, to search for the string 'RC=0000' in all jobs starting with 'TESTJOB' you would use the following command:

zowe zos-jobs search job 'TESTJOB*' --search-string 'RC=0000'
