librbd/migration/NativeFormat: refactor source spec parsing

In preparation for not instantiating NativeFormat and losing a copy of
the source spec JSON object in m_json_object, refactor the parsing code
to use only const methods (which std::map's operator[] isn't) and local
variables where possible.

librbd/migration/NativeFormat: do pool lookup instead of creating io_ctx

A Rados instance is sufficient to map the pool name to the pool ID,
no need to involve an IoCtx instance as well.  While at it, report
distinctive errors for a non-existing pool and an invalid JSON value
for pool_name key cases.

librbd/migration: make SourceSpecBuilder::parse_source_spec() static

In preparation for divorcing NativeFormat from FormatInterface and
changing when/how src_image_ctx is created, make parse_source_spec()
independent of src_image_ctx.  The "invalid source-spec JSON" error is
duplicated by the "failed to parse migration source-spec" error, so
just get rid of the former to spare having to pass CephContext to
parse_source_spec().

Although main rados nightlies are scheduled to run weekly, they

they finally do, most of the jobs die (likely due to waiting in the
queue so long).

This commit increases the priority of main rados runs since
these are most important for debugging new failures. To compliment this
increase in priority, this commit also decreases the frequency of squid
rados runs from twice a week to once a week, since once is more than
enough. It also decreases the prioirity of squid runs.
