Sql tz fix

[jakeheut]

Description

This pull request addresses issues regarding _validate_sql_recovery_point and _date_time_conversion:

• SQL recoveries don't allow seconds when specifying time, causing a failure every time an export has a non-zero value for seconds. This pull request adds seconds to _validate_sql_recovery_point and _date_time_conversion to work for SQL functions without breaking vSphere functionality.
• _validate_sql_recovery_point converts for time zone unnecessarily when specifying "latest" which breaks automation if run on a different time zone then the Rubrik Cluster.

Motivation and Context

This change fixes sql_db_export during these 2 scenarios:

1. The function is ran from a client on a different time zone then the Rubrik Cluster.
2. The export targeted has a non-zero second for time.

How Has This Been Tested?

This has been tested on a Rubrik Cluster running 5.3.2-p3-19174.

The following functions have been tested due to being modified directly or having a sub-function modified:

• sql_instant_recovery
• get_sql_db_files
• vsphere_live_mount
• vsphere_instant_recovery
