Use the ConvertSqlTimeColumnToEpochMs function to convert any native
datetime data type or epoch time (millisecond precision).
Refactored mysql implementation to make it more similar to postgres
and mssql implementations.
Added $__timeEpoch macro function with same implementation as $__time.
Added possibility to use a time column named time in addition to
the currectly supported time_sec.
Additional tests and update of existing.
Added test dashboard.
Use the ConvertSqlTimeColumnToEpochMs function to convert any native
datetime data type or epoch time (millisecond precision).
Additional tests and update of existing due to timezone issues
running postgres on UTC and dev environment on non-utc.

Use the ConvertSqlTimeColumnToEpochMs function to convert any native

Additional tests and update of existing due to timezone issues
running MSSQL on UTC and dev environment on non-utc.
Update stored procedures test to handle more parameters.
Update test dashboard.
Removes the macro function . Macro functions should not do UTC/timezone conversion - they should
work in the same way as postgres and mysql datasource implementations.
Grafana and Microsft SQL Server should be run on servers with UTC timezones.
Earlier the division of interval was done using whole numbers resulting in that important information
was lost/too many time series merged to the same group. Now using division of floating point and rounding
up to solve the problem
This seems like a niche feature which can be solved by defining multiple queries. In the future
we'll probably add support for defining series name by alias field similar to how other datasources
have solved that, e.g. prometheus.
This changes forks the mysql part of the Macaron session middleware.
In the forked mysql file:
- takes in a config setting for SetConnMaxLifetime (this solves wait_timeout
problem if it is set to a shorter interval than wait_timeout)
- removes the panic when an error is returned in the Exist function.
- retries the exist query once
- retries the GC query once
For MySQL, setting this to be shorter than the wait_timeout MySQL setting
solves the issue with connection errors after the session has timed out for
the connection to the database via xorm.
- Resolved alerts will be sent to the AM the first time they move
from Alerting to OK
- Errors are forwarded
- NoData is not ignored anymore
- The summary annotation is set (with the alertname)
- The image annotation is set (when available)
