* Improve influxdb provider
- reduce public funcs. We should not make things public that don't need to be public
- improve tests by verifying remote state
- add influxdb_user resource
allows you to manage influxdb users:
```
resource "influxdb_user" "admin" {
name = "administrator"
password = "super-secret"
admin = true
}
```
and also database specific grants:
```
resource "influxdb_user" "ro" {
name = "read-only"
password = "read-only"
grant {
database = "a"
privilege = "read"
}
}
```
* Grant/ revoke admin access properly
* Add continuous_query resource
see
https://docs.influxdata.com/influxdb/v0.13/query_language/continuous_queries/
for the details about continuous queries:
```
resource "influxdb_database" "test" {
name = "terraform-test"
}
resource "influxdb_continuous_query" "minnie" {
name = "minnie"
database = "${influxdb_database.test.name}"
query = "SELECT min(mouse) INTO min_mouse FROM zoo GROUP BY time(30m)"
}
```
