      .PARAMETER Session
      Specify an UnitySession Object.
      .PARAMETER Name
      Name of new schedule.
      .PARAMETER type
      Type of snapshot schedule rule. Values are:
      - N_HOURS_AT_MM: Snap every <interval> hours, at <minutes> past the hour. Supported parameters: interval (required), minutes (optional, default 0).
      - DAY_AT_HHMM: Specify a list of <hour[,...]> to snap one or more times each day at <minutes> past the hour. Supported parameters: hours (at least one required), minutes (optional).
      - N_DAYS_AT_HHMM: Snap every <interval> days at the time <hours>:<minutes>. Supported Parameters: interval (required), hours (optional, exactly one), minutes (optional).
      - SELDAYS_AT_HHMM: Snap on the selected <daysOfWeek>, at the time <hours>:<minutes>. Supported parameters: daysOfWeek (at least one required), hours (optional, default 0), minutes (optional, default 0).
      - NTH_DAYOFMONTH_AT_HHMM: Snap on the selected <daysOfMonth>, at the time <hours>:<minutes>. Supported parameters: daysOfMonth (at least one required), hours (optional, default 0), minutes (optional, default 0).
      .PARAMETER minute
      Minute frequency for the snapshot schedule rule.
      .PARAMETER hours
      Hourly frequency for the snapshot schedule rule.
      .PARAMETER daysOfWeek
      Days of the week for which the snapshot schedule rule applies.
      .PARAMETER daysOfMonth
      Days of the month for which the snapshot schedule rule applies.
      .PARAMETER interval
      Number of days or hours between snaps, depending on the rule type.
      .PARAMETER isAutoDelete
      Indicates whether the system can automatically delete the snapshot based on pool automatic-deletion thresholds. Values are:
      - $True: System can delete the snapshot based on pool automatic-deletion thresholds.
      - $False: System cannot delete the snapshot based on pool automatic-deletion thresholds.
      .PARAMETER retentionTime
      (Applies when the value of the isAutoDelete attribute is false.) Period of time in seconds for which to keep the snapshot.
      .PARAMETER accessType
      For a file system or VMware NFS datastore snapshot schedule, indicates whether the snapshot created by the schedule has checkpoint or protocol type access
      .PARAMETER Confirm
      If the value is $true, indicates that the cmdlet asks for confirmation before running. If the value is $false, the cmdlet runs without asking for user confirmation.
      .PARAMETER WhatIf
      Indicate that the cmdlet is run only to display the changes that would be made and actually no objects are modified.
      .EXAMPLE
      New-UnitySnapSchedule -Name 'SCHEDULE01' -Type N_HOURS_AT_MM -Interval 12 -Minute 30
 
      Create snapshot schedule named 'SCHEDULE01'. Snap every 12 hours, at 30 minutes past the hour.
