Bridget McErlean a42284ed17 Add Tilt configuration to debug using Delve (#3189)
* Add Tilt configuration to debug using Delve

This change adds support to run the Velero process in Tilt using
[Delve](https://github.com/go-delve/delve).
This does not include support for debugging the Velero process in the
restic pods, just in the Velero deployment.

For an optimal debugging experience, this change also introduces a new
flag (`DEBUG`) to the `hack/build.sh` script to enable a "debug" build
of the Velero binary. This flag, if enabled, will build the binary
without optimisations and inlining. Disabling optimisations and inlining
is recommended by Delve.

Two configuration options have been added to the Tilt settings. The
first, `enable_debug`, is to control whether debugging should be
enabled. If enabled, the process will be started by Delve, and the Delve
server port (2345) will be forwarded to the local machine.
The second option, `debug_continue_on_start`, is to control whether the
process should "continue" when started by Delve or should be paused.
By default, debugging is disabled, and if in debug mode, the process
will continue.

* Add spaces around keyword args

Starlark prefers spaces around `=` in keyword arguments:
