Allow setting description in logdna_view resource

[mriedem]

The UI shows that you can set a description for a view:

For views with an alert attached, we'd like to be able to populate a description with a link to a runbook for dealing with the alert so that can get into the alert details in PagerDuty.

Would it be possible to expose setting the description for the logdna_view resource so that information can also get into the alert via the pagerduty_channel?

Our API currently does not surface the description for views. https://docs.mezmo.com/log-analysis-api#create-view

This would be a necessary prerequisite to make this available in Terraform. I'll raise this issue internally to see if a change like this is viable.
