missing delete_measurement method

[Andreone]

There's a delete_series method on InfluDB client, but no delete_measurement.
With InfluxDB Enterprise 1.5, deleting a serie requires a restart of the influx service to clean the index. Deleting a measurement does not requires a restart.

Yeah, there are many query methods missing.

As a workaround, this should work:

name = "name_of_measurement"
client.execute("DROP MEASUREMENT #{name}"), db: client.database)

[dmke]

Ah, scratch that. Client#execute is private. I don't encurage client.send(:execute, "DROP MEASUREMENT #{name}", db: client.database) ;-)

I will add some convenience methods later this week (unless, of course, you're faster opening a PR).

[dmke]

v0.6.1 will have #list_measurements and #delete_measurement(name) methods.
