[YDB#963] [V7.0-005] [GTM-F135382] New v70005/audit_gde_facility-gtmf135382 test for Audit GDE facility

Release Note (http://tinco.pair.com/bhaskar/gtm/doc/articles/GTM_V7.0-005_Release_Notes.html#GTM-F135382) says:

When LGDE is specified as an option for the AZA_ENABLE facility, GDE logs all commands. For example, an entry like the following in $gtm_dist/restrict.txt enables GDE logging via a local socket:

AZA_ENABLE:LGDE:/path/to/sock/file/audit.sock The AZA_ENABLE facility enables the use of the $ZAUDITLOG() function which GDE uses for logging commands. Refer to GTM-F170998 for information on the $ZAUDITLOG() function and for other possible use in application audit logging. Previously, GDE did not provide an audit logging option. (GTM-F135382)
